Cover illustration: The title compound, (acetonitrile-N)pentacarbonyltungsten(0) is an important precursor in the synthesis of complexes containing the W(CO)5 fragment. The coordination of the tungsten atom is slightly distorted octahedral, with the acetonitrile ligand bound end-on to the W(CO)5 moiety. The trans-influence of the acetonitrile ligand becomes noticeable by a significantly shorter W-C bond of 1.975 (5) Å compared to the cis-carbonyls with W-C bond lengths between 2.023 (5) and 2.056 (5) Å.
