| Description |
diphenylphosphinomethyl)
ethane trichalcogenide ligands, [CH3C(CH2P(X)Ph2)3], where X= Se(a), S(b) and
O(c) in 1:1 (metal:ligand) molar ratio to afford hexa-coordinated complexes of the type �2-(X,X)-
[Ru(CO)2Cl2P3X3] (1a–c). The complexes 1a–c exhibit two equally intense �(CO) bands in the range
1979–2060cm−1 indicating cis-disposition of the two terminal carbonyl groups. The values of �(CO)
frequencies containing different ligands, in general, follow the order: P3O3 >P3S3 >P3Se3 which may be
explained in terms of ‘Soft–Hard’ (Ru(II)–O) and ‘Soft–Soft’ (Ru(II)–S/Se) interactions. The complexes have
been characterized by elemental analyses, mass, 1H, 31P, 77Se and 13C NMR spectroscopy. The thermal
stability of the complexes has also been studied
