Abstract

Single crystals of the title complex Na4 (NH4)10[Nd4Mo29O100(H2O)16]·34H2O obtained from the reaction of (NH4)6Mo7O24 and Nd (NO3)3, crystallize in themonoclinic, space group C2/c, with a= 19. 556(8), b= 43. 22 (2), c= 20. 389 (7) A,β= 117. 43(3)°, V= 15297(10) A3, Z=4, Dc= 1. 331g· cm-3, F(000) =5824, μ=1. 875 mm-1, final R(wR) = 0. 0816 (0. 2039) for 6128 unique intensity data [I≥2σ(I)]. In the molecule, each Nd heteroatom is coordinated by nine oxygen atoms with amono-capped square-antiprism configuration[1], while the Mo (VI) ions have severaldifferent coordination numbers (4, 5 and 6) with different configurations such as tetra-hedron, distorted square pyramid and octahedron respectively.
