Abstract
The title compound [N(CH3)(4)](4) [H5PMo5V9O42]. 3.5H(2)O was synthesized b y hydrothermal method and its structure was determined with single crystal X-ray analysis, The cluster anion is a bicappcd Keggin polyanion, two vanad ium atoms are distributed at two capping metal atom positions. The crystal is monoclinic, space group C2/c with a = 1.284 8(4) nm, b = 2.366 4(4) nm, c = 2.113 6(4) nm, beta = 90.69(2)degrees, V = 6.425(4) nm(3), Z = 4, D-c = 2.07 g . cm(-3), R = 0.066, R-W = 0.069, S = 1.33, (Delta/sigma)(max) = 0. 04, (Delta rho)(max) = 91 e . nm(-3).
