Abstract

The title complex crystallized in triclinic system with space group P1;Mr=5862. 35 a= 17.04(1), b= 18. 989(5), c= 24. 240(6) A ;a= 100. 18(2), β=92. 24(3), γ= 113. 04(3)°; V=7054(6) A3, Z=2, Dc= 2. 664 g. cm-3, F(000) =5306, μ= 4. 036 mm-1 and final R= 0. 0763 and Rw= 0. 2176 for 15951 reflections [Ⅰ2δ(I)]. The Nd(Ⅲ) coordinated with 9 oxygen atoms forms a mono-capped square-antiprism configuration, while the Mo (Ⅵ) ions have several different coordinationnumbers such as 4, 5 and 6 with different configurations such as tetrahedron, distortedsquare pyramid and octahedron respectively.
