Catena-Poly[[aqua-bis-(4-formyl-benzoato-κ(2) O (1),O (1'))cadmium]-μ-pyrazine-κ(2) N:N'].

ABSTRACT: The polymeric title compound, [Cd(C8H5O3)2(C4H4N2)(H2O)] n , contains two 4-formyl-benzoate (FB) anions, one pyrazine mol-ecule and one coordinating water mol-ecule; the FB anions act as bidentate ligands. The O atom, the aldehyde H atom and the benzene ring of one of the FB anions are disordered over two positions. The O atoms were freely refined [refined occupancy ratio 0.79 (2):0.21 (2)], while the aldehyde H atoms and the benzene ring atoms were refined with fixed occupancy ratios of 0.8:0.2 and 0.5:0.5, respectively. In the ordered FB anion, the carboxyl-ate group is twisted away from the attached benzene ring (A) by 22.7 (8)°. In the disordered FB anion, the corresponding angles are 15.6 (10) and 11.4 (11)° for rings B and B', respectively. Benzene rings A and B are oriented at a dih
