  New Carbaalanes Containing Clusters of Aluminum and Carbon Atoms:  (AlEt)₈(CCH₂C₆H₅)₅H, (AlMe)₈(CCH₂C₆H₅)₅(C⋮C-C₆H₅), and (AlMe)₇(CCH₂CH₃)₄H₂. Quantum Chemical Characterization

  摘要：

  The open carbaalane cluster (AlEt)(7)(C=CHC6H5)(2)(CCH2C6H5)(3)H (2), which was obtained in our group only recently, reacted with an excess of diethylaluminum hydride with hydroalumination of its C=C double bonds and formation of the compound (AlEt)(8)-(CCH2C6H5)(5)H (4). The central cluster of the product comprises a cube of eight Al atoms, five faces of which are occupied by C-benzyl groups; the sixth face is bridged by a hydrogen atom. The carbaalane (AlMe)(8)(CCH2C6H5)(5)(C=CC6H5) (5) was obtained by hydroalumination of Me2AlC=CC6H5 by Me2AlH at 60 degreesC. Its structure is similar to that of 3, but the bridging hydride ligand has been replaced by an ethynyl group, which is coordinated to four Al atoms acid shows a quite unusual C=C stretching vibration of 1956 cm(-1). The first carbaalane possessing only aliphatic substituents, (AlMe)(7)(CCH2CH3)(4)H-2 (6), was obtained by the reaction of Me2AlC=CCH3 with Me2AlH. Its structure contains an Al7C4 cluster, which is quite similar to that of the closo-borate [B11H11](2-) All intense emission of a cluster vibration characteristic for carbaalanes was assigned at about 325 cm(-1) in the Raman spectra. The structure and bonding of arachno-type cluster compounds related to 4 were investigated by quantum chemical calculations. A delocalized multicenter bonding situation was verified with only weak direct Al-Al interactions.

  Me2(MeCC)2Alm (M = Li, Na) and Me2(Me3CCC)2AlLi were synthesized, and found to form stable 1 : 1 complexes with 1,4-dioxane. The low conductance and other properties indicate more covalent bonding to the alkali metal by the alkynyl groups than by the alkyl groups in Me4AlM.

  The demarcation for the formation of cationic aluminium complexes is the transition between the use of chloride as a ligand (Me2AlCl–NH2But 1) and the relatively more polarizable bromide [Me2Al(NH2But)2]Br 2} as determined by X-ray diffractometry.

  阳离子铝复合物的形成界限是使用氯作为配体（Me2AlCl–NH2But 1）与使用相对更易极化的溴化物[Me2Al(NH2But)2]Br 2}之间的过渡，由X射线衍射测定。
