Penta-coordinated ruthenium or osmium catalysts for metathesis reactions of olefins, which are cationic complexes represented by formulas I, II or III: Image wherein M is ruthenium or osmium; each of X1 and X2, which may be the same or different, is an optionally substituted C3 - C20 hydrocarbon group having an allyl moiety as an end group bonded to the central metal atom M, or X1 and X2 together form a group, optionally substituted, which results from dimerization of an alkene and has at each end an allyl moiety bonded to the central metal atom M, L1 is a neutral electron donor ligand; L2 is a carbene group; L3 is a neutral electron donor ligand which may be the same as or different from L1, or L3 is a halide group; L11 is a neutral electron donor ligand; L12 is a solvent molecule capable of coordination to the central metal atom M; L13 is an alkyl group; L14 is an alkyl, a carbene, a solvent molecule capable of coordination to the central metal atom M, or a halide; L ~ L is a bidentate ligand coordinated to the central metal atom M through two atoms which may be the same or different, each of which is independently selected from the group consisting of a phosphorus atom, a nitrogen atom and an arsenic atom; A is a counter anion coordinated to the central metal atom M but only weakly coordinated so that A is not bonded as a ligand to the central metal atom M; and n is 1 or 2.
