- W2080224327 abstract "The reaction of MIå (MZr, Hf) with trimethylphosphine in benzene solution leads to different compounds, Zrl4(PMe1)1 (1) and Hfl4(PMe1)2→(2). According to the single-crystal X-ray diffraction study. Zr in 1 has a capped trigonal antiprismatic coordination by four I and three P atoms. Superposition of two molecules, Hfl4(PMe1)1 and Hfl4(PMe1)2 in 1:1 ratio has been found in 2. The reduction of MX4 with 1 equiv. of Na/Hg amalgam in the presence of PMe, afforded bioctahedral M(III) complexes Hf2I6(PMe1)4 (3), Zr2Br6(PMe4)4 (4) and Ti2l6(PMe4)4 (5). The compounds 3 and 4 are characterized by a cis-cis arrangement of phosphine ligand with respect to two M centres with direct M…M bounds at distances of 3.33 A (3) and 3.20 A (4). There is no TiTi bond in the cis-trans complex [5 with the Ti…Ti distance of 4.30 A. The reduction of Hfl4 with 2 equiv, of Na/Hg amalgam in the presence of PMe, resulted in the isolation of Hf(II) complex, (μ-η6,η6-C6H6)Hf2)4(PMe4)3·C6H6 (6. The complex 6 contains dinuclear molecules with two-sided coordination of benzene by two Hf atoms. The strong deformation of coordination benzene in the form of a twisted boat (CC 1.45=1.46 A) is explained by steric repulsion from the neighbouring PMe, ligands." @default.
