catena-Poly[[bis(α-thenoyltrifluoroacetonato)copper(II)]-μ-1,4-di-4-pyridyl-2,3-diazabuta-1,3-diene]

In the one-dimensional title polymer, [Cu(C8H4F3O2S)2(C12H10N4)]n or [Cu(L)2(tta)2] [tta is α-thenoyl­trifluoro­acetonato and L is 1,4-bis­(4-pyrid­yl)-2,3-diaza-1,3-butadiene], Cu2+ lies on a center of inversion. It is axially coordinated by two pyridyl N atoms from two different L ligands and equatorially coordinated by four O atoms from two chelating tta ligands. The ligand L propagates the one-dimensional chain structure by serving as a bridging ligand between two Cu octa­hedra via Cu—N coordinate bonds.
