Chemical formula: [Ni(C 4 H 7 N 2 O 2 ) 2 ]. Dimethylglyoxime loses one hydrogen ion to form two dimethylglyoximato ions, each of which is coordinated to nickel(II) by two nitrogen atoms. Official name: bis(dimethylglyoximato)nickel(II). It is obtained by mixing nickel(II) acetate and a hot saturated ethyl alcohol solution of dimethylglyoxime. Red needle-shaped crystals in an orthorhombic system. It sublimes at 250°C and decomposes at 310°C. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
