Organic Section

The present volume continues the aim of Structure Reports to present critical accounts of all crystallographic structure determinations. Details of the arrange ment in the volumes, symbols used etc. are given in previous volumes (e. g. 41B or 42A, pages vi-viü). University of Guelph, G.

Young 2 ARRANGEMENT To find a particular organic or organometallic compound consult one of the indices (subject, permuted subject, formula or permuted formula) at the end of Part 2 of this volume. The general arrangement follows the classification used in the Cambridge Crystallographic Data Base and is: aliphatic or open chain compounds; open chains with N, S; benzene derivatives; c cyclic hydrocarbons; condensed ring systems; heterocyclic compounds; carbohydrates; amino acids; natural products; molecular complexes; organometallic compounds - B, Si, P, AJJ, Sb, groups lA, IIA, III, IV, VI; transition meta! complexes - . .
