Inhoud:
A Nd(III) complex with β-alanine of empirical formula [Nd(β-ala)3-2H2O]Cl3 has been syn-thesised and characterised. The crystal structure of the complex was studied using single-crystal X-ray diffraction methods. When heated the complex loses water molecules and subsequent decomposition to Nd2O3 takes place. The complex crystallizes in space group P21/c with a =10.846(3), b=19.552(4), c = 9.464(3)Å, β=102.02(3)°, Z = 4. The structure consists of polymeric chains connected through hydrogen bonds. Neodymium(III) ions in the chains are bonded alternately through two and four carboxylate bridges from β-alanine molecules. Carboxylate groups are bidentate-chelating and tridentate chelating-bridging. Two molecules of water complete the coordination number of Nd(III), which is nine.
