The complex was prepared by refluxing a methanol solution of Ni(NO/sub 3/)/sub 3/ . 6H/sub 2/O and dimethyl glyoximatic acid for 10m; refluxing for an additional 2h after the addition of sodium methoxide in methanol, filtering while warm, followed by evaporation of the solution under vacuum. X-ray diffraction study of a single crystal placed it in the orthorhombic space group P2,2,2, with a = 13.175(1), b = 13,652(2), c = 12.031(3)A; z = 4, and P/sub calcd./ = 1.378 g/cc. The nickel atom was found to be in an almost square-planar configuration. The HCQD/sup -/ ligand coordinates to the N via N and O donor atoms rather than the common N-N coordination characteristic of other ..cap alpha..-dioxime ligands. Bond lengths and bond angles are also included.
