Abstract

The complex Na10[LaSiW11O39(H2O)4]2?2H2O was synthesized and crystallized in monoclinic,space group P21/n with cell parameters: a=17.9786(9), b=23.5940(2), c=13.1289(8), β=90.141(2)°, V=5569.1(6)3, Mr=6336.60, Z=2, Dc=3.779g/cm3, (MoKa)= 0.71069? =23.533mm-1, F(000)=5488, T=293(2)K. The final refinement for 8404 observed reflections with I 2s (I) gave R = 0.0595 and wR = 0.1366. Both lanthanide cations are coordinated by nine oxygen atoms in a distorted squareantiprism environment. The LaO bond lengths are from 2.52(1) to 2.63(2).
