Resumen:
Infrared spectra of the coordination compounds [MG2(py)2], M(II) = Co, Ni, Cu and Zn; G = glycolato, py = pyridine, have been fully assigned by means of py and py-d5 and glycolato ?-OH and ?-OD (G-d) labelling as well as metal ion substitution in the 4000-70 cm-1 region. The crystal structure of the Ni(II) compound is presented and the spectra of the compounds are discussed on the basis of their structure and their bonding to the glycolato and pyridine ligands. Vibrational frequencies obtained for the Ni(II) compound are compared to those obtained by calculations carried out using the Gaussian 94 program package.
