✦ Synopsis

The binuclear complexes [ {M(C0)5}21.c-pyrazine] (M = 0, W) were readily prepared by heating the mononuclear compounds in an inert atmosphere. The spectroscopic data demonstrate that the M(CO)5 moieties in these complexes have retained C,, symmetry. The two allowed metal to pyrazine CT transitions could be detected and assigned with the use of the Resonance Raman effect.

of these binuclear compounds has been noted by Herberhold et al. without further characterization of the structure and bonding. These properties will be reported in this article.

The preresonance Raman spectra of [W(CO),pyridazine] are reported and related to the properties of the W to pyn'dazine CT transition.
