The relative orientations of adjacent polymeric chains (Mercury 3.3, capped sticks) in the crystal structures of (a) [CdCl2(2-pyz)2]n (1) and (b) [CdBr2(2-pym)2]n (5) linked via one single-point N—H⋯O hydrogen bond forming extended C(4) chains. [CdBr2(2-pyz)2]n (2) and [CdI2(2-pyz)2]n (3) exhibit the same supramolecular architecture as 1, and [CdI2(2-pym)2]n (6) the same as 5.
