Abstract
The crystal and molecular structures of the titled scandium(III) (1) and yttrium(III) chloroacetates (2) were determined by the single-crystal X-ray diffraction method. 1 is monoclinic, with the space group P21/n, a=12.148(4), b=8.860(5), c=11.028(4) Å, and β=103.31(3)°. In 1, the metal atom has the hexa-coordinated octahedral geometry, and any pair of the neighboring metal atoms are bridged by three bidentate carboxylate ions, forming an infinite chain. 2 is isomorphous with the heavy lanthanoid salts, [Ln3(ClCH2CO2)9(H2O)4]n·nH2O (Ln=Gd–Yb), and its crystal structure closely resembles that of the erbium(III) complex.Keywords
