The monomeric title Zn(II) complex, [Zn(C(7)H(4)BrO(2))(2)(H(2)O)(2)], contains two 4-bromo-benzoate (BB) ligands and two coordinated water mol-ecules 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 octa-hedral, with the two aqua ligands arranged cis. Hydrogen bonding involving the carboxyl-ate O atoms has an effect on the delocalization in the carboxyl-ate groups. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the c axis and stacked along the b axis.
