Aqua-[1,8-bis-(pyridin-2-yl)-3,6-dithia-octane-κN,S,S',N']copper(II) dinitrate acetonitrile monosolvate.

In the title compound, [Cu(C(16)H(20)N(2)S(2))(H(2)O)](NO(3))(2)·CH(3)CN, the Cu(II) atom displays a distorted square-pyramidal coordination, in which a water mol-ecule occupies the apical position and the basal plane is formed by two N atoms and two S atoms of a 1,8-bis-(pyridin-2-yl)-3,6-dithia-octane ligand. The crystal packing is stabilized by O-H⋯O and C-H⋯O hydrogen bonds.
