Compounds of the type add activated alkynes (MeO2CC=CCO2Me, CF3CCCF3, HCCCO2Me) to give complexes of 1,3-dithiole-2-ylidenes.The unstable intermediate can be trapped by a similar reaction.The cyclic dithiocarbene complexes thus formed undergo ring opening with Co2(CO)8 to give tetrahedral methylidyne clusters, one of which has been characterized by X-ray structure analysis. 3-CSC(CF3)C(CF3)μ2-S)> crystallizes orthorhombic (a 1058.9(3), b 1584.1(5), c 3380.2(8) pm) with 8 molecules in the unit cell, ρ 2.08 mg/mm3.

New complexes of the type (M=Cr, Mo, W) have been isolated from the reaction of the ligand, 1,2-bis(di-p-tolylphosphino)ethane (dptpe) with Group VI metal hexacarbonyls in a suitable solvent such as methylcyclohexane.The resulting complexes on treatment with an excess of pyridine produces the mixed ligand complexes , whereas the reaction of 3-allyl)(MeCN)2> (X=Cl, Br) with dptpe gives 3-allyl)(dptpe)>.The formulation of the structures of these complexes follows from elemental analyses and 1H NMR, 31P NMR and IR spectral studies.Carbonyl force constans have been calculated from the ν(CO) streching frequencies by the Cotton and Krainhanzel method.
