Axial substitution and bridge formation by the cyano group in bis(dimethylglyoximato)cobalt(III) complexes

Abstract

Using the title complexes as building blocks, the formation of polynuclear compounds with cyano bridges of the types CoCNCo and AgCNCo was studied. In the first case, a solid polymer was obtained with better conducting properties than the mononuclear compounds, thus confirming the ability of the cyano group to act as a mediator in electron transfer. In the latter case, a variety of compounds was obtained as well as the recently-reported isocyano derivative, due to a rather complex equilibrium existing in aqueous solution.
