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

The reaction of cadmium acetate dihydrate with 2-acetyl­pyridine (4-phenyl­thio­semicarbazone) yielded the title compound, [Cd(C₁₄H₁₃N₄S)₂]. The Cd^II 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].
