The discrete complex [(Cul)2 (pyzCN)4] (1) and the coordination polymers 1∞ [CuI(pyzCN)] (2) and 3∞ [(CuX)3 (pyzCN)2] (3, 4; X = Br, Cl) may be prepared from the respective copper(I) halide CuX and 2-cyanopyrazine (pyzCN) by self-assembly in acetonitrile solution at 100- 120°C. Whereas 2 exhibits 1 [Cul] staircase double chains as its characteristic substructure, the three-dimensional networks of 3 and 4 contain single zigzag CuX strings. The influence of the copper(I) halide on both the
