Bis{4-phenyl-1-[1-(pyridin-2-yl-κN)ethylidene]thiosemicarbazidato-κ²N¹,S}cadmium

Abstract

The reaction of cadmium acetate dihydrate with 2-acetyl­pyridine (4-phenyl­thio­semicarbazone) yielded the title compound, [Cd(C14H13N4S)2]. The CdII atom is six-coordin­ated in a distorted octa­hedral environment by two deproton­ated thio­semicarbazone ligands acting in a tridentate chelating mode through two N and one S atoms, forming metalla-rings. In the crystal, mol­ecules are connected through inversion centers via pairs of N—H⋯S inter­actions, building a one-dimensional hydrogen-bonded polymer along [0-1-1].
