ABSTRACT

We have investigated the spatial and electronic structure of the complexes [Co(AAm)4(H2O)2](NO3)2 and Co(AAm)4Cl2 by electronic spectroscopy. The complex of cobalt nitrate with acrylamide (AAm) has a pseudooctahedral structure in the crystalline state and in organic solvents, and the metal-ligand bonds are covalent to a significant degree. For the complex of cobalt chloride with AAm, a change in the spatial structure is characteristic upon going from the crystal (tegragonally distorted octahedron) to the solution (tetrahedron). For a Co(AAm)4Cl2 single crystal, we determined the sequence of the energy levels with the ground-state4A2g-term. The high values of the McClure parameters, taking into account the contributions of the ligands to the σ and π bonds, are evidence for coordination of the acrylamide through the oxygen atom.
