Özet

The monomeric title Zn-II complex, [Zn(C7H4BrO2)(2)(H2O)(2)], contains two 4-bromobenzoate ( BB) ligands and two coordinated water molecules around a Zn-II atom on a twofold rotation axis. The BB ions act as bidentate ligands, with two very dissimilar coordination distances. The sixfold coordination around the Zn-II may be described as highly distorted octahedral, with the two aqua ligands arranged cis. Hydrogen bonding involving the carboxylate O atoms has an effect on the delocalization in the carboxylate groups. In the crystal structure, intermolecular O - H center dot center dot center dot O hydrogen bonds link the molecules into chains parallel to the c axis and stacked along the b axis.
