Molecular Structures and Dimensions

This volume is the fourteenth classified bibliography of organic, organometallic and metal complex crystal structures prepared by the Cambridge Crystallo- graphic Data Centre and published jointly with the International Union of Crystallography. The previous thirteen volumes covered the years 1935-81; the majority of references in the present volume pertain to structure analyses reported in the literature during 1981 and 1982. A few structures reported prior to 1981 and omitted in earlier volumes are also included. Volume 14 contains 4094 references to 4001 distinct chemical compounds with 2162 cross-references. Some 90% of these references were obtained by direct in-house scanning of 51 major journals; the remaining material was located by searching Chemical Abstracts and Bulletin Signa/etique. The table below summarizes the cut-off dates for the 25 direct-scan journals yielding most entries in Volume 14. The fully classified Chemical Diagram Index, first presented in Volume 13, is continued here. Volume 14 contains 3912 chemical structural diagrams, repre- senting 98% of the compounds. The reasons for the omission of some diagrams are noted in the Introduction. This new index provides a rapid visual overview of compounds studied in 1981-82 and will, we hope, add greatly to the usefulness of the annual Bibliographies. The textual indexes in Volume 14 continue the system established in Volumes 9-13 and in the special volume Guide to the Literature 1935-76. The latter volume presents a set of cumulative indexes to the contents of Bibliographic Volumes 1-8.
