The title compound, [Cu(C(8)H(7)O(3))(2)(C(10)H(8)N(2))]·H(2)O, is comprised of a Cu(II) ion, two 3-meth-oxy-benzoate ligands, a 2,2'-bipyridine (bipy) ligand and one uncoordinated water mol-ecule. The Cu(II) ion and the water O atom lie on a twofold axis. The Cu(II) ion exhibits a six-coordinate distorted octa-hedral geometry, with two N atoms from the bipy ligand [Cu-N = 1.9996 (16) Å] and four O atoms from two 3-meth-oxy-benzoate ligands [Cu-O = 1.9551 (15) and 2.6016 (16) Å]. The mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.
