Synthesis and Spectroscopic Characterization of H3CoRu3(CO)12. Crystal and Molecular Structure of the C(3v) Isomer.
Abstract
The reaction of HCoRu3(CO)13 with H2 in refluxing hexane gives the new cluster H3CoRu3(CO)12 in 75% yield. Infrared and H(1) NMR spectra indicate that the cluster exists in two isomeric forms. The structure of one isomer has determined by single-crystal x-ray diffraction. The CoRu3 core of the molecule defines a distorted tetrahedron with three carbonyls terminally bound to each metal atom. The hydride ligands were located by difference Fourier techniques and bridge the three Ru-Ru bonds. The overall symmetry of the cluster is approximately C sub 3v. Spectral evidence indicates that the second isomer contains a bridging CO ligand and three non-equivalent hydrogens. The interconversion of the two isomers and the various hydrogen exchange processes have been monitored by H(1) NMR spectroscopy and the exchange mechanisms are discussed.
