Abstract:
A novel one-dimensional polyoxovanadium borate (H 3NCH 2CH 2NH 3) 3[(VO) 12O 4{B 8O 17(OH) 4} 2{Na(H 2O)} 2]·(H 3O) 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 V 12 ring, constructed from edge-sharing VO 5 square pyramids. Two {B 8O 17(OH) 4} 14- polyborate chains fill in the cavities formed by the V 12 ring. The [(VO) 12O 4{B 8O 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 μ 2-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. All rights reserved.
