In the past the aim of Structure Reports has been to present critical reports on all work of crystallographic structural interest, whether it is derived directly from X-ray, electron, or neutron diffraction, or even indirectly from other experiments. The reports were in- tended to be critical and not mere abstracts, except in some cases when a brief indication of the content of a paper of related interest was included in the form of an abstract. In selecting topics for reporting, the criterion 'of structural interest' was freely interpreted in terms of what was topically interesting. However, the amount of Iiterature covering matters of structural interest became so large that this policy could no Ionger be followed, and from Volume 28 onwards, critical reports are given only on actual structure deter- minations. Only in this way was it possible to keep yearly volumes to a fairly uniform and usable size. Starting with Volume 30, Structure Reports is produced in a new format by photo-offset printing from typed manuscript with unjustified lines. At the time when the decision for this change was taken, the cost of setting the manuscript in type was becoming so high as to render the cost of individual subscription prohibitive. At that time automatic typing methods giving justified lines, etc.

The present volume continues the aim of Structure Reports to present critical accounts of all crystallographic structure determip. ations. The increase in the number of crystal structure papers (now about 2000 per year in the Organic Section) has prompted a minor change in format, which increases the information density per page, hopefully without any loss of clarity. Details of the arrangement in the volumes, symbols used etc. are given in previous volumes (e. g. 41 B or 42A, pages vi-viii). J. TROTTER University of British Columbia Vancouver, Canada 14 September 1978 [VI] STRUCTURE REPORTS SECTION III ORGANIC COMPOUNDS Edited by G. Ferguson with the assistance of M. Currie D. F. Rendle J. Iball S. J. Rettig A. L. Macdonald S. N. Scrimgeour W. C. Marsh J. C. Speakman M. Napier ARRANGEMENT To find a particular organic compound the subject index or the formula index should be used. The general arrangement is: aliphatic or open-chain compounds; open chains with N, S; benzene derivatives; cyclic hydrocarbons; condensed ring systems; heterocyclic compounds; carbohydrates, amino-acids, natural products; molecular complexes; organometallic compounds - B, Si, P, As, Sb, groups lA, IIA, III, IV, VI; transition metal complexes - w-complexes, other ligands. Only com­ plete structure analyses are described; compounds for which only lattice para­ meters are determined, and those which have been described only in preliminary communications and for which details will appear at a later date, have not been reported.
