alpha-Polonium coordination networks constructed from bis(imidazole) ligands

Abstract

Two types of bis(imidazole) ligands-1,4-bis(imidazol-1-ylmethyl)benzene (bix) and 1,4-bis(imidazolyl)-2-butyne (bib)-have been used to bridge octahedral metal centres and form simple cubic networks. Crystal structures of Cd(bix)3(ClO4)2, Cd(bix)3(NO 3)2, Zn(bib)3(BF4)2 and Co(bib)3(NO3)2 reveal that all possess the α-polonium topology and are triply interpenetrating. © The Royal Society of Chemistry.The Royal Society of Chemistry 2002.
