Bis[(5-bromo-pyridin-2-yl)methano-lato-κ(2) N,O]copper(II) monohydrate.

In the title compound, [Cu(C6H5BrNO)2]·H2O, the Cu(II) ion has a square-planer N2O2 coordination environment. Slipped π-π stackings [centroid-centroid distances: 3.625 (3), 3.767 (3), 3.935 (3) and 4.255 (3) Å] between pyridine rings and Cu⋯π inter-actions (centroid-to-Cu(II) distance: 3.56 Å) between Cu(2+) ions and pyridine rings lead to a layered arrangement parallel to (010). Inter-molecular Br⋯O inter-actions [Br⋯O distances: 2.904 (3) and 3.042 (3) Å] and O-H⋯O hydrogen bonds form a three-dimensional network structure.
