Abstract

Abstract: A series of isostructural 3D lanthanoid coordination polymers, {[Ln(µ4 -cbpy)2 ]Br·xsolvent}n (Ln = La(1 ), Pr(2 ), Nd(3 ), Sm(4 ), Gd(5 ), Tb(6 ), Dy(7 ) and Ho(8 ), (H2 cbpy)Br = 4-carboxy-1-(4-carboxybenzyl)pyridinium bromide), have been solvothermally synthesized and characterized by single-crystal X-ray diffraction, IR and elemental analysis. Powder X-ray diffraction (PXRD) and thermal analyses (TG, DTA and DTA) of 1 –8 were also investigated. The single crystal X-ray diffraction analyses revealed that 1 –8 were isostructural and crystallized in the monoclinic space group C 2/c. In the complexes, each cbpy – acts as a tetrakis(monodentate) to connect to four Ln(III) ions. A pair of Ln(III) ions are coordinated by four carboxylate oxygen atoms to form paddle-wheel {Ln2 (RCOO)4 } secondary building units which are connected by four cbpy – ligand to form a 3D structure with scu topology.
