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 P 2 1 / n with a = 6.988(2), b = 17.615(6), c = 12.564(4) Å, β = 90.790(5)°. 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.
