New chemistry of oxo trinuclear, metal–metal bonded niobium compounds
Abstract
Reaction of Nb2Cl6(tetrahydrothiophene)3 with aqueous acids provides a general route to oxo trinuclear, metal–metal bonded species such as [Nb3(µ3-O)2(SO4)6(H2O)3]5–, [Nb3(µ3-O)2(O2CMe)6(tetrahydrofuran)3]+, and [Nb3(µ3-S)(µ2-O)3(NCS)9]6–.
