Compounds of cobalt and dimethylglyoxime were first prepared by Tschugaeff during the course of his classical researches on the α-dioximes (1). The simplest of these compounds corresponded to the formula [Co (NH3)2 (DH2)2] X2, DH2 representing a molecule of dimethylglyoxime and X a univalent anion. Tschugaeff prepared other compounds in which one or more of the ammonia groups were replaced by aniline or pyridine.
