Cobalt(II) complexes with the non-steroidal anti-inflammatory drug mefenamic acid in the presence or absence of nitrogen donor heterocyclic ligands (2,2'-bipyridine, 1,10-phenanthroline or pyridine) have been synthesized and characterized with physicochemical and spectroscopic techniques. The experimental data suggest that mefenamic acid acts as deprotonated monodentate ligand coordinated to Co...

a novel pyridine-2,6-dicarboxylic acid mixed ligands complex of formula [co(no3)2].6h2o has been obtained by the reaction of pyridine-2,6-dicarboxylic acid with cobalt nitrate and 1,10-phenanthroline on heating in water. the structures of [co(pydc)(phen)(h2o)](pydch2).4h2o receptors, and their complexes were optimized using dft method at the b3lyp/3-21g** level. the highest occupied molecular o...

The reaction of a cobalt(II) salt with 4-(dimethyl-amino)pyridinium hydro-bromide perbromide yielded the title compound, (C(7)H(11)N(2))[CoBr(3)(C(7)H(9.1)Br(0.9)N(2))]. In the anion, the Co(II) atom is coordinated in a distorted tetra-hedral geometry by three Br atoms and the pyridine N atom of a bromine-substituted 4-(dimethyl-amino)pyridine mol-ecule, whose formation probably results from an...
