Space groups of some coordination compounds of cobalt

Abstract

The unit cell dimensions and space groups of some coordination compounds of cobalt(III) are presented. The cell dimensions are measured from rotation photographs and the space-group absences are determined from the zero- and first- layer Weissenberg photographs taken about the principal axes using Fe K-alpha radiation. The compounds are sodium salt of cobalt(III) ethylenediaminetetraacetate tetrahydrate, cobalt(III) tris-glycinate dihydrate, cobalt(III) bis-dimethylglyoximino diaminethiocyanate, and cobalt(III) bis- dimethylglyoximino diamineperchlorate.
