| Abstract: | Zn(H2O)6](N-inicO)2 is an ionic compound made up of hexaaqua metal cations and isonicotinate N-oxide anions. It forms an isomorphic series with the corresponding Mg2+, Fe2+, Co2+ and Ni2+ compounds.In Cd(N-inicO)2(H2O)2]n complex, coordination takes place through the NO oxygen and one of the (COO) oxygens with ligand forming thus a double bridge between Cd2+ ions. The structure is an endless chain stretching diagonally through the unit cell.The coordination polyhedron in both compounds is almost undistorted octahedron. |
