The present volume continues the aim of Structure Reports to present critical ac­ counts of all crystallographic structure determinations. Details of the arrangement in the volumes, symbols used etc. are given in previous volumes (e. g. 41B or 42A, pages vi-viii). University of Guelph, G. FERGUSON Guelph, Ontario, Canada 18 January 1986 [VI] STRUCTURE REPORTS SECTION III ORGANIC COMPOUNDS Edited by S. N. Scrimgeour with the assistance of J. C. Barnes G. Ferguson J. lball C. H. Morgan T. J. R. Weakley B. C. Williams C. C. Wilson D. W. Young [1] 2 ARRANGEMENT To find a particular organic or organometallic compound the subject index or formula index at the end of Part 2 of this volume 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, Ill, IV, VI; transition metal complexes - ~-complexes, other ligands; inorganic anions which have orp,anic counter ions. Only complete structure analyses are described, and those which have been reported in preliminary communications and for which details will appear at a later date, have not been described here. 3 ALIPHATIC CARBOXYLIC ACID DERIVATIVES BROMOFLUOROACETIC ACID C H BrF0 2 2 2 R.
