A Comprehensive Experimental and Theoretical Study on the[{(η5-C5H5)2Zr[P(µ-PNEt2)2P(NEt2)2P]}2O Crystalline System
PublicationThe structure of tetraphosphetane zirconium complex C52H100N8OP10Zr21 was determined by single crystal X-ray diffraction analysis. The crystal belongs to the monoclinic system, space group P21/c, with a = 19.6452(14), b = 17.8701(12), c = 20.7963(14)Å, α = γ = 90°, β = 112.953(7)°, V = 6722.7(8)Å3, Z = 4. The electronic structure of the organometallic complex has been characterized within the framework of Quantum Chemical Topology....

Formation of polyphosphorus ligands mediated by zirconium and hafnium complexes
PublicationThe reactions of R2P–P(SiMe3)Li (R = tBu, iPr, iPr2N) with [Cp2MCl2] (M = Zr, Hf), [Cp∗CpZrCl2] and [CpZrCl3] yielded polyphosphorus (mainly hexaphosphorus) compounds which can be viewed as intermediates between R2P–P(SiMe3)Li and derivatives of 1,2,3,4-tetraphosphabicyclo[1.1.0] butane. Thus R2P–P(SiMe3)Li can act as a building block for the formation of the P2 ligand and the R2P–P(P2) and R2P–P(P2)P–PR2 moieties. Solid state...
