Reaction of bis(2-pyridylmethyl) ether with [Mo(CO)(3)(MeCN),I in MeCN gives the title compound, [MO(C12H12N2O)(CO)(3)], (I), as a yellow crystalline product. Compound (I) has been characterized by H-1 NMR and IR spectroscopy, and single-crystal X-ray crystallography. In contrast with other examples of low-valent early transition metal complexes of ethers, the ether linkage of (I) appears relatively inert. Nevertheless, the weak donor property of the ether ligand is evidenced by a trans effect manifested as a short Mo-CO bond length for the carbonyl ligand trans to the ether ligand.
