Synthesis and characterization of zinc(II) oxydiacetate (oda) complexes. Crystal structures of [{Zn(oda)·0.3H2O}n], [Zn(oda)(bipy)(H2O)]·2.5H2O and [Zn(oda)(phen)(H2O)]·1.5H2O (bipy = 2,2′-bipyridine, phen = 1,10-phenanthroline)
Three novel zinc(II) oxydiacetate (oda) compounds [{Zn(oda)·0.3H2O}n] 1, [Zn(oda)(bipy)(H2O)]·2.5H2O 2 (bipy = 2,2′-bipyridine) and [Zn(oda)(phen)(H2O)]·1.5H2O 3 (phen = 1,10-phenanthroline) have been synthesized and their structures determined by single-crystal X-ray diffraction methods. Compound 1...

| Sumario: | Three novel zinc(II) oxydiacetate (oda) compounds [{Zn(oda)·0.3H2O}n] 1, [Zn(oda)(bipy)(H2O)]·2.5H2O 2 (bipy = 2,2′-bipyridine) and [Zn(oda)(phen)(H2O)]·1.5H2O 3 (phen = 1,10-phenanthroline) have been synthesized and their structures determined by single-crystal X-ray diffraction methods. Compound 1 consists of polymeric sheets formed by ZnO5 units bridged by carboxylate groups in anti-syn conformation along the z axis; 2 and 3 are mononuclear with the zinc atoms in distorted octahedral ZnN2O4 co-ordination geometries. Thermal decomposition of the compounds under an oxygen atmosphere affords ZnO at ca. 500°C. |
