Abstract
New coordination compounds, (bmmpaH)[Fe(pydc)2] (EtOH)0.8(H2O)0.2 (1), (8QH) [Fe(pydc)2] H2O (2), (2ampyH)2[Mn(pydc)2] H2O (3), (2ampyH)[Cr(pydc)2](2ampy)0.5 H2O (4), [Co(H2O)5--(pydc)Co(pydc)] 2H2O (5), [Ni(pydcH)2] H2O (6), and [Cu(pydcH)2] (7), where bmmpa, 8Q, 2ampy, pydcH2 are 5-bromo-6-methyl-2-morpholinepyrimidine-4-amine, 8-hydroxyquinoline, 2-amino-6-methylpyridine, and pyridine-2,6-dicarboxylic acid, respectively, have been synthesized and structurally characterized by elemental analyses, infrared, UV spectroscopic methods, and X-ray crystallography. Metal ions of 1 and 5 are six-coordinate with distorted octahedral geometries. Compound 1 is an anionic mononuclear complex and 5 is a binuclear compound constructed from cationic and anionic parts. The crystal data of 5 reveal that the cationic part is formed by five terminal waters and one -carboxylate oxygen O2 from the anionic portion and the anionic complex is built from two deprotonated (pydc)2 moieties. In the compounds, pydcH2 is tridentate by one nitrogen of pyridine ring and two oxygens of carboxylate.
