Synthesis and crystal structure of a cadmium complex with isonicotinate

The cadmium(II) complex, [Cd(iso)(2)(H2O)(4)](where iso is the anion of isonicotinic acid), has been synthesized and characterized by element analysis, thermal analysis and IR spectroscopy. An X-ray crystal structure reveals that the cadmium ion is trans-octahedral with two pyridyl nitrogens and two aqua oxygens in equational positions and two aqua oxygens in axial positions. The complex forms a three-dimensional network through intermolecular hydrogen bonds.
