Cambridge Crystallographic Data Base

Fragment search in the Cambridge Crystallographic Data Base reveals 127 hits out of 42381 entries (state May 1985) having dimethyl sulfoxide as the search query and allowing for the presence of metal atoms. In absence of such elements, the number of hits is reduced to 27. 

Figure 2. Schematic diagram of the hydrogen-bond structure in the crystal structure of gentiobiose (GENTOSOl REFCODE in Cambridge Crystallographic Data Base). The arrows indicate infinite chains. Distances are H—O in A, angles are 0-H—O in degrees. The covalent 0-H bond lengths have been normalized to 0.97 A.

Henceforth, crystal structure analyses of carbohydrates (class 45), amino acids (class 48), purines and pyrimidines (class 44) and nucleosides and nucleotides (class 47) are referenced by means of their Cambridge Crystallographic Data Base REFCODES. All other crystal structure analyses are referenced in the General Index. 

A reason that hydrated crystals are so plentiful in the Cambridge Crystallographic Data Base is that water is the solvent of choice for crystallization, just as it is the solvent of choice for biological processes. 

The Cambridge Crystallographic Data Base was an indispensible source of data and we are grateful for permission to use the Refcodes for indexing.

I should like to thank Dr. Sharon Bellard of the Cambridge Crystallographic Data Base and Dr. Paul Raithby for their invaluable assistance in obtaining structural data, and Dr. Ken Seddon for kindling and nurturing an interest in these ligands. 

This chapter is concerned with the solid state structures of arsenic, antimony and bismuth compounds, which in general contain at least one bond between carbon and the Group 15 element. In selecting material for discussion, I have been greatly aided by the availability of the Cambridge Crystallographic Data Base. The period under consideration covers effectively the years between 1981 and 1992.
