| 摘 要： | Recently, the thermal decomposition of heteronuclear complexes has become apromising method for the preparation of di- or tri-metallic oxides because the complex as precursor has the special microstructure, the controlled stoichiometry of the metals and lower decomposition temperature 1. In order to investigate Ba-V-O system, which has the special magnetic behavior 2, we synthesized the title complex as the precursor of this material. On the other hand, microporous constructions existing in…

| Abstract: | A new heteronuclear complex, dimer [(2-OH2)2Ba2(H2O)4][VO2(tpa)]24H2O (tpa: 2,4,6-tripicolinate trianion), was synthesized and structurally determined by X-ray diffraction technique where all hydrogen atoms have been located directly. The coordination geometry of V(V) ion is a distorted trigonal bipyrimid and that of Ba(II) ion is a capped square antiprism. One 2-O bridging bond and two hydrogen bonds act between the coordination geometries. A 1-D extended porous construction containing 20-member cavities is observed in the crystal. |
