The far infrared spectra of Ni (pyridine)4X2 and Ni(γ-picoline)4X2 (X = CI, Br and I) have been measured. The Ni-X and Ni-N stretching bands have been assigned based on isotopic shifts due to the 58Ni-62Ni, pyridine-pyridine-d5, and Cl-37Cl substitutions.

Far Infrared Spectra

Infrared spectra of some triarylphosphine and diphosphine complexes of gallium (III) chloride, bromide, and iodide have been recorded in the range 600–200 cm−1 and assignments of gallium–halogen stretching vibrations made. The number and frequencies of the ν (Ga–X) vibrations are consistent with monomeric structures for the triarylphosphine complexes in the solid state. Possible structures for the diphosphine complexes are discussed.

Far Infrared Spectra

Cobalt(II) and nickel(II) halide complexes with thiomorpholin-3-thione and thiazolidine-2-selenone have been prepared. Infrared and far infrared spectra, electronic spectral studies, and magnetic susceptibility measurements indicate that the cobalt derivatives are tetrahedral in structure, nickel chloro- and bromo-thiomorpholin-3-thione derivatives are octahedral while [Nits2I2] and all nickel thiazolidine-2-selenone complexes have a pseudo-tetrahedral symmetry. The probable site of bonding in the ligands is nitrogen in all the complexes studied here, except the nickel derivatives of thiazolidine-2-selenone. These results are confirmed by n.m.r. measurements. Spectroscopic parameters for the complexes have been calculated and compared against similar chromophores containing MN2X2 and MS2X2 chromophores.
