The triangulo-(V3Cl3) unit is shown to form easily in solutions from m
ononuclear vanadium(II) compounds:such as [VCl2(tmeda)(2)] and structu
ral studies show that this unit is contained in a trigonal bipyramidal
arrangement with either chloride ions or methoxide ions at the apices
, as in [V3Cl3(mu(3)-Cl)(2)(tmeda)(3)](+), [V3Cl3(mu(3)-OMe)(2)(tmeda)
(3)](+) and[V3Cl3(mu(3)-OMe)(2)(depe)(3)](+)
