Synthesis and characterization of heteroscorpionate dioxo-tungsten(VI) complexes
摘要:
Twelve new dioxo W(VI) complexes of a family of heteroscorpionate ligands of the type [(L)WO2Y], where L = N2X ligand and Y = Cl or OR, have been synthesized and characterized. With the more sterically bulky ligands we show that these complexes exist as isolable cis and trans isomers and compare the rate of such isomerization with their corresponding dioxo Mo(VI) analogs.
