Synthesis, crystal and molecular structure of [Sn(η4-P2C2But2)]: the first non transition metal 1,3-diphosphacyclobutadienyl compound
Abstract
Treatment of [Zr(η5-C5H5)2(PCBut)2] with SnCl2 led to the novel monomeric (1,3-diphosphacyclobutadienyl)tin(II) half sandwich complex [Sn(η4-P2C2But2)] which has been characterised by multinuclear
