Data on the synthesis and the IR spectroscopic and X-ray diffraction analyses of new complexes of yttrium chloride with carbamide (Ur), [Y(Ur) 4 (H 2 O) 4 ]Cl 3 ( I ) and [Y(Ur) 6 (H 2 O) 2 ]Cl 3 ( II ), and with acetamide (AA), [Y(AA) 5 (H 2 O) 2 ]Cl 3 ( III ), are presented. The coordination of the ligands occurs through the oxygen atoms. For complexes I and II , the coordination polyhedra of the Y atoms are distorted tetragonal antiprisms. For structure III , the coordination polyhedron of the Y atom is a distorted pentagonal bipyramid. The coordination of four Ur molecules in complex I does not change their planar structure, and two Ur molecules in structure II have the dihedral angle N-C(O)-N different from 180°. The chloride ions are in the external sphere. Many hydrogen bonds are observed in the structures of complexes I – III .
