Poly[[bis(-1,2-bis{[2-(2-pyridyl)-1H-imidazol-1-yl]methyl}benzene)lead(II)] dithiocyanate]

R.-H. Cui and Y.-Q. Lan

Abstract: The title Pb^II coordination polymer, {[Pb(C₂₄H₂₀N₆)₂](SCN)₂}_n, was obtained by the reaction of Pb(CH₃COO)₂·3H₂O, KSCN and 1,2-bis{[2-(2-pyridyl)-1H-imidazol-1-yl]methyl}benzene (hereafter L). Each L molecule coordinates to two Pb^II cations through the four aromatic N atoms, thus acting as a bridging bis-bidentate ligand. The Pb^II cations, which lie on inversion centres, are bridged by four L molecules, forming a two-dimensional (4,4)-sheet. The SCN^- anions act as counter-ions and are uncoordinated.
