X-ray diffraction investigation of Nd(N(CN)/sub 2/)/sub 3/ x 2PO(NMe/sub 2/)/sub 3/
The results of an x-ray diffraction investigation of the neodymium complex Nd-(N(CN)/sub 2/)/sub 3/ x 2OP(NMe/sub 2/)/sub 3/ have been presented. The crystals are monoclinic: a = 12.787(6), b = 17.731(9), c = 15.302(5) A, ..gamma.. = 114.84(3)/sup 0/, Z = 4, space group P2/sub 1//n. The structure was refined by the least-squares method in the anisotropic approximation on the basis of 4505 reflections with I greater than or equal to 3sigma(I) to R = 0.032. The structure is formed from infinite corrugated networks consisting of neodymium atoms coordinating two OP)NMe/sub 2/)/sub 3/ molecules, and three bidentate bridging dicyanamide groups. The coordination number of neodymium is 8, and the coordination polyhedron is a distorted bicapped trigonal prism. Some aspects of the crystal chemistry of dicyanamide complexes have been discussed.
