Reaction of [Ru3(CO)12] with 2-(chloromethyl)pyridine, syntheses of pyrid-2-ylacetyl ruthenium(II) complexes and crystal structure of [RuCl(C5H4N-2-CH2CO) (CO)(PPh3)2]

The cycloruthenated pyrid-2-ylacetyl complex [{RuCl(C₅H₄N-2-CH₂CO)(CO)₂} ₂] (1) was obtained by reaction of [Ru₃(CO)₁₂] with an excess of 2-(chloromethyl)pyridine in refluxing toluene. Subsequent reaction of 1 with two equivalents of triphenylphosphine in refluxing benzene afforded the bis(phosphine) derivative [RuCl(C₅H₄N-2-CH₂CO)(CO)(PPh₃) ₂] (2). X-ray analysis of 2 shows that the complex is monomeric with the ruthenium atom coordinated by ring nitrogen and acyl carbon atoms from the cycloruthenated pyrid-2-ylacetyl group, cis chlorine and carbonyl carbon atoms, and trans phosphorus atoms, to form a distorted octahedral geometry.
