Di-μ-azido-κ(4) N (1):N (1′)-bis­({1-[(E)-phen­yl(pyridin-2-yl-κN)methyl­idene]thio­semi­carbazidato-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 mol­ecule. In the crystal, the binuclear mol­ecules are linked by an N—H⋯N hydrogen bond into a ribbon running along the a axis.
