A linear tetranuclear vanadium–oxygen assembly
Abstract
The reaction of [VO(salen)] with controlled quantities of species able to extract the oxygen atom, such as trityl fluoroborate or fluoroboric acid–diethyl ether (1/1) leads to the novel tetranuclear cation [{V(salen)}4(µ-O)3]2+, which contains a linear vanadium–oxygen chain.
