Abstract

The title compound (H3NCH2CH2NH3)4[(VO)6(B10O22)2]·(H3O)7 1 has been synthe- sized by the hydrothermal method and determined by X-ray crystallography. Crystallographic data: monoclinic, space group C2/c, a = 20.250(4), b = 13.448(3), c = 21.655(4) ?, β = 97.05(3)°, Mr = 851.74 (C4H30.5B10N4O28.5V3), V = 5852(2) ?3, Z = 8, Dc = 1.933 g/cm3, μ = 1.057 mm-1, F(000) = 3436, R = 0.0500 and wR = 0.1442 for 4511 observed reflections with I 2σ(I). The structure con- sists of [(VO)6(B10O22)2]15- cluster anions that have a central band of six trans-edge-sharing VO5 square pyramids capped by two [B10O22]14- polyborate ligands. Other characterizations are also describ- ed by elemental analysis, IR spectrum and thermal analysis.
