title: [1-(2-Oxidobenzyl-idene)-4-phenyl-thio-semicarbazidato-κO,N,S](pyridine-κN)copper(II).
abstract: In the structure of the title compound, [Cu(C(14)H(11)N(3)OS)(C(5)H(5)N)], the Cu(II) atom exhibits a slightly distorted square-planar CuN(2)OS coordination polyhedron consisting of a phenyl O, an azomethine N and a thio-amide S atom from the tridentate thio-semicarbazonate dianion, and the N atom of a pyridine mol-ecule. The thio-semicarbazonate ligand exists in the thiol tautomeric form as an E isomer. Rotational disorder of the pyridine and phenyl rings in a 1:1 ratio of the respective components is observed. An extensive network of weak N-H⋯S, C-H⋯O, C-H⋯N and C-H⋯S hydrogen-bonding inter-actions consolidates the structure.
