Di-μ-azido-κ(4)N(1):N(1')-bis-({1-[(E)-phen-yl(pyridin-2-yl-κN)methyl-idene]thio-semi-carbazidato-κ(2)N(1),S}copper(II)).

In the title compound, [Cu(2)(C(13)H(11)N(4)S)(2)(N(3))(2)], the Cu(II) cation is N,N',S-chelated by the deprotonated Schiff base ligand and is coordinated by the azide anion, while an N atom from an adjacent azide anion bridges the Cu(II) cation at the apical position with a longer Cu-N distance of 2.533 (3) Å, completing the distorted N(4)S square-pyramidal coordination geometry. A pair of azide anions bridge the two Cu(II) cations, forming a centrosymmetric binuclear mol-ecule. In the crystal, the binuclear mol-ecules are linked by an N-H⋯N hydrogen bond into a ribbon running along the a axis.
