Metal-containing building units (ORTEP-style plots obtained using Mercury 3.3) equipped with pyrazinone (pyz) and pyrimidinone (pym) ligands, (a) [CdCl2(2-pyz)2]n (1) and (b) [CdBr2(4-pym)2]n (5), respectively. The crystal structures of [CdBr2(2-pyz)2]n (2) and [CdI2(2-pyz)2]n (3) are isostructural with each other and with 1, and the structure of [CdI2(4-pym)2]n (6) is near-identical to that of 5.
