Abstract

The title complex (Nd (C18H20N2O4) (NO3)3] was prepared and char-acterized by X-ray diffraction. The complex crystallizes in monociinic system, spacegroup P21/n, a= 14. 220(5) A, b= 11. 777(3) A, c= 14. 812(4) A, β= 105. 28(3)°, V= 2393(2) A3, Mr= 658. 63, Z=4, Dx= 1. 828 g/cm3, F(000) = 1308, thefinal R= 0. 053, Rw= 0. 065. In the complex the coordination number of Nd(Ⅲ) is 10with the geometry of a bicapped square antiprism. All of the coordination atoms areoxygen atoms.
