  摘要：

  针对丙烯二聚催化剂的Ni K边EXAFS研究表明，这些催化剂是通过NiCl2(PEt3)2溶液与Al2Me3Cl3和AlEt3在-40 °C下相互作用形成的。结果表明第一配位层包含C和P原子；约2.97 Å处的Ni‥Al壳层暗示存在Ni–C–Al相互作用，这可能稳定了镍中心。

  Reaction of bzo2.18S6 (2,3,11,12-dibenzo-1,4,7,10,13,16-hexathiacyclooctadeca-2,11-diene) with Fe, Co, Ni and Cu salts yields the corresponding metal complexes [M(bzo2-18S6)]n+. Their trifluoromethanesulfonate salts were characterized by spectroscopic and electrochemical methods and the structure of [Ni(bzo2-18S6)][B(C6H5)4]2 was elucidated by X-ray structure determination. It crystallizes in space group P2(1)/n with a = 1497.8(4), b = 1096.5(4), c = 1772.5(5) pm, beta = 104.26(2)-degrees, Z = 2 and D(calc) = 1.36 g/cm3; R = 0.061, R(w) = 0.041. The nickel centre is surrounded by the six sulfur atoms of the ligand in a slightly distorted octahedron. The Ni-S distances indicate a ligand compression effect of bzo2-18S6. The different electrochemical behaviour of the [M(bzo2-18S6)]n+ complexes is discussed.

  The reaction of nickel(II) acetylacetonate trimer with 1,3-bis(2,4,6-trimethylphenyl)imidazolium chloride, [IMesH]Cl, leads to the formation of the remarkable double salt 11MesHJANiC141.11Me5HICI 2. (or alternatively [IMesH](3)[NiCl4]Cl). The solid-state structure of this species was determined by a single X-ray diffraction study. The molecular parameters of the ions are unremarkable, but this double salt crystallizes in the chiral space group P6(3) despite the achiral nature of all the ions: the chirality arises from the helical arrangement of the imidazolium mesityl groups. Additionally, the crystal contains hydrophobic channels of ca. 4.5 angstrom diameter, and there are extensive H-bonding interactions in the crystal. The double salt reacts with potassium tert-butoxide to give the known bis-N-heterocyclic carbene complex trans(Ni(IMes)(2)Cl-2], 3. (C) 2014 Elsevier Ltd. All rights reserved.
