Abstract: 
ID rare earth thiolate amide coordination polymers can be obtained by an activator-controlled in situ ligand synthesis in reactions of molten 2-mercaptobenzimidazole with lanthanide metals. Catalytic amounts of mercury activate the metals and induce a C-S bond cleavage that in situ forms 2,2'-bibenzimidazole. The latter then reacts as a linker ligand to give (1)(infinity)[Ln(2)(MbiM)(4)(Bbim)], Mbim(-) = C7H5SN2-, BbiM(2-), C14N4H82-. In addition cinnabar is formed. Stoichiometric amounts of mercury cause the complete transformation of 2-mercaptobenzimidazole to 2,2'-bibenzimidazole. Instead of thiolate coordination polymers the reaction then yields sulfur-free monomeric bibenzimidazolate complexes (BimH(2))(+)-[Ln(BbimH)(4)](-), (BimH(2))(+) = C7H6N2+, BbimH(-) = C14N4H9-. Thus the amount of Hg also controls the dimensionality of the products by defining the reaction path. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
