Diaquabis(5-methyl-1,2-oxazole-3-carboxylato-[kappa]2N,O3)cobalt(II) dihydrate

Y. Wang and J. Zhao

Abstract: In the title compound, [Co(C5H4NO3)2(H2O)2]·2H2O, the coordination polyhedron around the six-coordinate CoII ion is formed by two equatorial 5-methylisoxazole-3-carboxylate ligands in an N,O3-bidentate fashion through the isoxazole N atom and a carboxylate O atom, and by two axial water ligands. The asymmetric unit consists of half of the complex and one water molecule (the full comlex being completed by application of inversion). In the crystal, the water molecules participate in the formation of an intricate three-dimensional network of hydrogen bonds involving the coordinated water molecule and the carboxylate groups.
