Crystals of one organic compound of cobalt

Abstract

Cobalt-diamine-dimethylglucimine chloride was obtained by L.A. Chugaev and presented by him to the Mineralogical Institute for crystallographic research (see article). Goniometric measurements (on a university, goniometer by E. S. Fedorov) and optical observations in polarized light revealed that the crystals belonged to the tetragonal system, the class of which could not be determined.
