摘要

A three-dimensional cyano-bridged copper(II) complex, [Cu(dien)Ag(CN)(2)](2)[Ag-2(CN)(3)][Ag(CN)(2)] (1) (dien = diethylenetriamine), has been prepared and characterized by X-ray crystallography. Complex 1 crystallized in the monoclinic space group P2(1)/n with a = 6.988(2), b = 17.615(6), c = 12.564(4) Angstrom, beta = 90.790(5)degrees. The crystal consists of cis-[Cu(dien)](2+) units bridged by [Ag(CN)(2)](-) to form a zig-zag chain. The Ag atoms of the free and bridging [Ag(CN)(2)](-) link together to form additional infinite zig-zag chains with short Ag...Ag distances. The presence of Ag...Ag interactions effectively increases the dimensionality from a 1-D chain to a 3-D coordination polymer.
