Structure
Nickel(II) is square planar.[2] It is surrounded by two equivalents of the conjugate base (dmgH−) of dimethylglyoxime (dmgH2). The pair of organic ligands are joined through hydrogen bonds to give a macrocyclic ligand. The complex is distinctively colored and insoluble leading to its use as a chelating agent in the gravimetric analysis of nickel.
The use of dimethylglyoxime as a reagent to detect nickel was reported by L. A. Chugaev in 1905.[3]

gollark: If you have a good and simple design for some sort of interesting market mechanic I could integrate it in AutoBotRobot.
gollark: How would that work?
