Surface and Bulk Reactions of Solid Nickel Dimethylglyoximate with Electron-Active Gases

Abstract

The action of ammonia on the surface of solid nickel dimethylglyoximate Ni(HDm)d2 is reversible and is accompanied by a change in the electrophysical properties of the surface layer of the complex in proportion to the ammonia content in the air. The action of chlorine on the complex gives rise to bulk chemical reactions yielding the Ni(III) complex {[NiIII(HDm)2(H2O)]2Cl02}ClI2 with a bridging μ-dichloride group, which is further oxidized to a substance presumably containing such ligands as one dimethylglyoxime group and products of its oxidation by chlorine.
