摘要：

A series of isomorphous lanthanide complexes, having general formula M(PiC)3(TDTD)1.5 (M=Ce-Er, Yb and Y), was synthesized and characterized by microanalyses, infrared spectra and visible emission spectrum for the Eu complex. Crystal structures were determined for the Ce and Eu derivatives; for the other complexes only cell parameters were obtained and reported. The compounds crystallize with a monoclinic cell, space group P2(1)/c with Z=4. The metal ions are nine-coordinated with a tricapped trigonal prismatic coordination polyhedron, achieved via the bonding of three bidentate picrate units and three oxygens of the TDTD ligands. The TDTD moieties are shared by adjacent metal centers, forming three-dimensional polymers.
