Abstract

The i.r. spectra of MoO2X2L2 and MoO2X2L′ complexes (X = Cl or Br; L = dmf, Dmso, or pyo; L′= bipy or phen) have been compared in order to identify stretching and bending modes involving the molybdenum atom. For MoO2Cl2·2dmf, assignment of bands has been assisted by calculation of vibration frequencies through normal-co-ordinate analysis. The spectra of all the adducts are consistent with a cis–trans–cis-octahedral arrangement of the terminal oxygen atoms (Ot), halogens, and ligand oxygen atoms (O1), respectively, about the molybdenum. The more weakly bonded O1 atoms are thus co-ordinated trans to the strongly bonded Ot. There is a fairly regular relation between ligand donicity and the ν(Mo–Ot) frequency.
