Diene complex of lanthanum: the crystal structure of a diene-bridged dilanthanum complex, [LaI2(thf)3(µ-η4:η4-PhCHCHCHchph)LaI2(thf)3]

Abstract

Reaction of metallic lanthanum with 1,4-diphenylbuta-1,3-diene and iodine in THF results in the formation of the diene-bridged bis(diiodolanthanum) complex, [LaI₂(thf)₃(µ-η⁴:η⁴-PhCHCHCHCHPh)LaI₂(thf)₃]1, whose structure was characterized by X-ray crystallography.
