ChemInform Abstract
Single crystal XRD results for the title compound (III) reveal that the chlorine atom is in trans position to the nitrosyl group. (III) crystallizes in the monoclinic space group P21/c with Z = 4. The low temp. IR and Raman spectra of (I) and five compounds (II), separated by ion exchange chromatography, are assigned by normal coordinate analysis. Observed and calculated frequencies are in good agreement. The valence force constants fd for NO (13.86—13.93 mdyn/Å) and RuN (5.43—5.49 mdyn/Å) are nearly independent of the geometrical arrangement of the halogen ligands.
