Triaqua-1κO,2κ(2) O-bis­(2,2′-bipyridine)-1κ(2) N,N′;2κ(2) N,N′-chlorido-1κCl-μ-terephthalato-1:2κ(2) O (1):O (4)-dicopper(II) nitrate monohydrate

In the binuclear title compound, [Cu(2)(C(8)H(4)O(4))Cl(C(10)H(8)N(2))(2)(H(2)O)(3)]NO(3)·H(2)O, the two crystallographically independent Cu(II) ions have similar coordination environments. One of the Cu(II) ions has a square-pyramidal arrangement, which is defined by a water mol­ecule occupying the apical position, with the equatorial ligators consisting of two N atoms from a 2,2′-bipyridine mol­ecule, one carboxyl­ate O atom from a terephthalate ligand and one O atom from a water mol­ecule. The other Cu(II) ion has a similar coordination environment, except that the apical position is occupied by a chloride ligand instead of a water mol­ecule. An O—H⋯O and O—H⋯Cl hydrogen-bonded three-dimensional network is formed between the components.
