Abstract: In the title compound, [Cu(C9H10N4S)(C2H3O2)]·H2O, the Cu atom adopts a slightly distorted square-planar coordination geometry. The 2-acetylpyridine thiosemicarbazone group is very close to planar. The computed bond valencies for the Cu centre are (Cu-N) = 0.349 and 0.404 valence units (v.u.), (Cu-S) = 0.627 v.u., and (Cu-O) = 0.483 v.u. There is an out of plane Cu-O(acetate) bond [2.639 (13) Å], which makes a contribution of 0.08 v.u. The computed valency of the Cu atom is thus 1.94 v.u. Hydrogen bonds between pairs of molecules create dimers.
