Title: Crystal structure of (tricarbamidotriacetato)erbium(III) monocarbamide, (Er(C/sub 2/H/sub 3/O/sub 2/)/sub 3/ x 30C(NH/sub 2/)/sub 2/) x OC(NH/sub 2/)/sub 2/

The crystal structure was determined for (Er(C/sub 2/H/sub 3/O/sub 2/)/sub 3/ x OC(NH/sub 2/)/sub 2/) x OC(NH/sub 2/)/sub 2/ which has insular structure consisting of (Er(C/sub 2/H/sub 32/)/sub 3/ x 30C(NH/sub 2/)/sub 2/) complexes and outer-sphere OC(NH/sub 2/)/sub 2/ molecules. The erbium ions are located in nonapical polyhedra formed by the acetate group oxygen atoms and the urea molecules. All the acetate groups and urea molecules are virtually planar and the acetate groups fall into the bidentate-cyclic class. The Er-O bond lengths for the coordinated urea molecules are shorter than for the acetate groups. The mean Er-O, C-O, C-C, and C-N bond lengths are 2.410, 1.26, 1.54, and 1.34 A, respectively. All the interatomic distances and bond angles are in good accord with literature values.
