Di-μ-azido-κ4 N1:N 1′- bis({1-[(E)-phenyl(pyridin-2-yl-κN)methylidene]thiosemi-carbazidato- κ2 N1,S}copper(II))

Abstract

In the title compound, [Cu2(C13H11N 4S)2(N3)2], the CuII 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 CuII cation at the apical position with a longer Cu - N distance of 2.533 (3) Å, completing the distorted N4S square-pyramidal coordination geometry. A pair of azide anions bridge the two CuII 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.
