Abstract: The asymmetric unit of the title compound, {[Zn(C₇H₇O₂)₂(C₁₀H₈N₂)]·4H₂O}_n, contains a highly distorted octahedral Zn^II metal center strongly coordinated by two N atoms of two 4,4'-bipyridine (4,4'-bipy) ligands and chelated by two 4-methylbenzoate anions. The crystallographic inversion center and glide plane present at the center of the C-C single bond of 4,4'-bipy, along with the cis coordination motif of the 4,4'-bipy, lead to one-dimensional zigzag chains. There are a large number of water molecules in the crystal structure, which also form one-dimensional chains through O-HO hydrogen bonds.
