fac-O3ClOMn(CO)3(diphos). The reaction of the latter complexes at room temperature with a variety of ligands L phosphines (PR3), phosphites (P(OR)3), pyridine (Py), acetonitrile (MeCN), tetrahydrothiophene (THT) or acetone (Me2CO) leads to the cationic species fac-[Mn(CO)3(diphos)L]ClO4 (or to the [Mn(CO)4(diphos))]ClO4, when L CO). When L is a phosphorus ligand, the cationic fac-tricarbonyls isomerize upon heating
