Abstract

The complex Sm[(C2H5O)2P(O)NHC(O)NHC(O)C6H5]3(ClO4) 3 · 3H2O was formed by the reaction of samarium perchlorate with N-(O,O-diethylphosphoryl)-N′-benzoylurea in ethylacetate and its X-ray crystal structure determined. The samarium atom is nine-coordinated by three phosphoryl oxygen atoms, three carbonyl oxygen atoms and three oxygen atoms from the water molecules, forming a distorted tricapped trigonal prism. Several important bond distances include Sm-O(1)(H2O) 2.471(6) Å, Sm-O(2)(H2O) 2.448(5) Å, Sm-O(3)(H2O) 2.442(5) Å, Sm-O(4)(phosphoryl) 2.394(4) Å, Sm-O(5) (carbonyl) 2.532(4) Å, Sm-O(6)(phosphoryl) 2.398(5) Å, Sm-O(7)(carbonyl) 2.543(4) Å, Sm-O(8)(phosphoryl) 2.398(5) Å and Sm-O(9)(carbonyl) 2.528(4) Å. © 1992.
