Abstract:
A novel one-dimensional polyoxovanadium borate (H3NCH 2CH2NH3)3[(VO)12O 4{B8O17(OH)4}2{Na(H 2O)}2]·(H3O)2(H 2O)6.5 (1) has been synthesized by the hydrothermal method and the structure determined by X-ray crystallography. The structure consists of a continuous contorted V12 ring, constructed from edge-sharing VO5 square pyramids. Two {B8O17(OH) 4}14- polyborate chains fill in the cavities formed by the V12 ring. The [(VO)12O4{B8O 17(OH)4}2]12- clusters are connected by unusual binuclear Na+ units into 1D chains. The binuclear Na + units are formed by two neighboring sodium atoms sharing two μ2-O from B-O-B. Each sodium atom is in a distorted octahedral geometry. Other characterizations are also described by elemental analysis, thermal analysis and IR, EPR spectra. © 2004 Elsevier B.V.
