摘要：
The complex Na-10[LaSiW(11)Q(39)(H2O)(4)](2). 22H(2)O was synthesized and crystallized in monoclinic, space group P2(1)/n with cell parameters: a = 17.9786(9), b = 23.5940(2), c = 13.1289(8)Angstrom, beta = 90.141(2)degrees, V = 5569.1(6)Angstrom (3), M-r = 6336.60, Z = 2, D-c = 3.779 g/cm(3), lambda (MoK alpha) = 0.71069 Angstrom, mu = 23.533 mm(-1), F(000) = 5488, T = 293(2)K. The final refinement for 8404 observed reflections with I>2 sigma (I) gave R = 0.0595 and wR = 0.1366. Both lanthanide cations are coordinated by nine oxygen atoms in a distorted squareantiprism environment. The La-O bond lengths are from 2.52(1) to 2.63(2)Angstrom.
