WebCorrect option is A) Dimethylglyoxime while acting as ligand has one negative charge so the oxidation number of Ni in given compound is +2. Hence, the IUPAC name of the compound is bis (dimethyl glyoximato) nickel (II). The geometry of the nickel(II) ion is square planar. 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.
