fac-Tricarbonyl[bis(2-pyridylmethyl) ether-N,O,N']molybdenum(0)

Reaction of bis(2-pyridylmethyl) ether with [Mo(CO)(3)(MeCN),I in MeCN give s 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 linkag e 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-C O bond length for the carbonyl ligand trans to the ether ligand.
