Synthesis and characterization of a novel oxo-disulfidotetravanadate(V) anion with a bridging tetrasulfido ligand [{V(O)(S2)2}2(µ2-S4){V(O)(S2)2}2]6–
Abstract
NH4[VO3] reacts with aqueous polysulfide solutions in the presence of 4,4′-bipyridine to yield the tetranuclear anion [V4S20O4]6– which contains four bipyramids connected via a zigzag S42– bridge.
