Structural Chemistry Indaba II
3-8 August 1997

Intermolecular Interactions

An international workshop organized by the South African Crystallographic Society in collaboration with the Commission on Structural Chemistry of the International Union of Crystallography.

IUCr Scientific Freedom Policy Statement
The Organising Committee of the Structural Chemistry Indaba shall observe the basic policy of non discrimination and affirms the rights of scientists throughout the world to adhere to or to associate with international scientific activity without restrictions based on nationality, race, colour, age, religion, political philosophy, ethnic origin, citizenship, language, or sex, in accordance with the Statutes of the International Council of Scientific Unions. At this conference no barriers will exist which would prevent the participation of bona fide scientists.

Indaba is an African term to describe a meeting to analyze a difficult problem from all angles

Theme - Intermolecular Interactions

Each of the invited lecturers will address a different aspect around the central theme of Intermolecular Interactions, starting with a critical overview of the assumptions common amongst structural chemists.

The idea of intermolecular interactions relates to the notion that materials in the bulk consist of weakly interacting units, or molecules, in the sense that intramolecular interactions are stronger than these, by orders of magnitude. In view of this it is argued that, by ignoring the weak interactions, the same molecular units that occur in the gas phase can be recognized in condensed phases. At the same time it is commonly accepted that solid materials exhibit many properties not apparent in other phases and acquired as a result of intermolecular interactions only. From both points of view the concept is rather ill-defined and of questionable importance. The problem relates to the model of choice to describe condensed phases. Defined as single quantum-mechanical systems there is no basis to distinguish between intra- and intermolecular forces. An intermolecular interaction is then defined only for the gas phase, where it is practically negligible in any case.

An attempt to distinguish between intra- and intermolecular interactions necessarily fails to recognize their interdependence and creates artifacts to be used later on as independent concepts, in terms of which to explain chemical behavior. In terms of deformation electron densities in crystals the distinction becomes even more vague and the definition of molecular units even more arbitrary.

Answers to these questions are probably not simple and different points of view can surely be formulated in all cases.

In this sense it provides a worthy topic for discussion at a special symposium in the spirit of the 1995 Small-molecules Indaba.

As with the Conference in August 1995, the second Indaba will be held in one of the most famous national parks in the world and the oldest one in Africa, the Kruger National Park. The same venue as before, the picturesque Skukuza camp, has been secured for the duration of the workshop.

One of the Park's main objectives is to maintain the ecosystem in its natural state and to offer the visitor an unrivaled experience of African wildlife.

While offering excellent accommodation facilities, the Park has retained a genuine African atmosphere - to the delight of the scores of visitors to the New South Africa.

The Climate is subtropical, with days normally sunny, warm and clear. During August, just before the onset of the warm African summer, the temperatures are moderate and pleasant. In this regard the South African author and nature lover, C Louis Leipoldt, wrote: "The ideal time to visit the Bushveld is in winter, from May to November. Then the climate is charmingly even: its mornings, when the sun tinges the tops of the bush, are delightfully crisp and cool; its noon is pleasantly but not relaxingly warm; its afternoons and evenings, stained by an all-too-brief afterglow with amazingly vivid colouring, are as mild and beautiful as a summer's night in Europe".

Excursions into the Park will give both delegates and accompanying persons many opportunities to view the unparalleled diversity of wildlife, including antelope, buffalo, elephant, lion, leopard, cheetah, wild dog, hyena, jackal, black and white rhinoceros, an exceptional variety of bird species and numerous other wild creatures. Skukuza is the Kruger Park's main camp. Dress code: Casual.

Johannesburg International Airport is well utilized by many major airlines from Europe, America and most other parts of the world. Normally trips from Europe last over 12 hours and are undertaken overnight, so leaving on the evening of Saturday the 2nd of August will allow you to arrive at JIA on Sunday the 3rd. Flights leaving JIA on the evening of Friday 8th August will arrive in Europe on the morning of Saturday 9th.

Travelers from Europe will feel no jet lag, but the Americas are 6 to 9 hours behind South Africa, while Asia is 2 to 10 hours ahead.

Visas may be required for some countries. Please make all travel arrangements with your local travel agents, but inform us of your arrival date, time, flight number etc.


Transport from the airport to the Skukuza camp in the Kruger National Park will be provided by coach for those that require it, at a cost of $100 per person. The bus trip will include refreshments and orientation information. For accompanying persons, and conference attendees, the bus will remain available for daily excursions into the park for the duration of the conference. The use of the bus for these excursions is included in the registration fee. The full bus fare is for the trips to and from the airport on the 3rd and 8th.

Please consider the information kiosk in the middle of the airport arrivals hall as the primary point of contact. There will be people with signs marked "Indaba II" to show you to the bus between 8:00 am and 10:00 am on the morning of Sunday 3rd August.

For current bus bookings look at the file distributed with the third indaba newsletter.

Final dates are:

JIA to Skukuza 10am on the morning of Sunday 3rd August
Park outings various times - see programme
Skukuza to JIA morning of Friday 8th August

Car Rental

Many international car rental companies (Avis, Hertz, Bugdget, etc.) are represented in South Africa. Attendees wishing to rent cars should apply through their local travel agents.

Accommodation available at Skukuza camp is in typical national park style. The rondawels are individual huts with hot and cold running water, linen service, and full ablution facilities. The number of beds per rondawel ranges from 2 to 6. To facilitate bookings the accommodation has been grouped into three categories.

The following prices are per person per night:

category price pp pn deposit
luxury (single) $60.00 $150.00
standard (sharing) $30.00 $75.00
basic (sharing) $25.00 $65.00

Malaria poses a health risk in the Kruger National Park. However, during the dry months, June to September, the risk of contracting malaria is low and procedures to prevent mosquito bites should provide sufficient protection. The use of prophylactic medicine should only be required from October to May. Please consult a local medical practitioner for detailed advice.

The shop at Skukuza camp apparently sells the appropriate anti-malaria drugs required. If you are unable to purchase any before arrival and wish to take anti-malaria drugs, please purchase some at the shop.
