  selenium resulted in the formation of novel dimeric compounds with the general formula [R2M(μ-SeR)]2 (M = In, R = Np (1); M = Ga, R = CH2SiMe3 (2)) in a nearly quantitative yield. Reaction of GaMes3 (Mes = 2,4,6-Me3C6H2) with 2 mol of elemental Se, and subsequent addition of 4-picoline (C6H7N), resulted in the isolation of three compounds, [(Mes)C6H7N·Ga-μ-Se]2 (3), (Mes)2C6H7N·GaSeMes (4), and Se2Mes2

  Compounds of the type R2Ga(bdk) (R = Me, Et, Mes (mesityl); bdk = 2,4-pentanedionato (acac); 1,1,1-trifluoro-2,4-pentanedionato (tfac), 1,1,1,5,5,5-hexafluoro-2,4-penatedionato (hfac), 2,2,6,6-tetramethyl-3,5-heptanedionato (tmhd)) have been prepared by multiple routes, including hydrocarbon elimination, metathesis, and ligand redistribution reactions, and fully characterized by elemental analyses, cryoscopic molecular weight studies in benzene, and IR and multinuclear NMR spectroscopic studies. An X-ray structural study of Mes(2)Ga(hfac) demonstrated four-coordinate gallium with sigma bonds to the two mesityl rings and to the two oxygen atoms of the beta-diketonate ligand. The Lewis acidities of the diorganogallium beta-diketonate derivatives toward NMe3 and/or pyridine were also-investigated. Two adducts, Me2Ga(hfac). NMe and Me2Ga(hfac). py, were stable to dissociation at room temperature and thus were fully characterized by elemental analysis, cryoscopic molecular weight studies in benzene, vapor pressure-temperature studies, and IR and multinuclear NMR (including variable temperature) spectroscopic studies. The compound Me2Ga(hfac). py was also characterized by an X-ray structural study. The structure involved five-coordinate gallium with one Ga-N, two (inequivalent) Ga-O, and two Ga-C bonds.

  The reaction of MMes(3) (M = Ga, In; Mes = 2,4,6-Me(3)C(6)H(2)) with CsF in acetonitrile yields the trimesitylfluorometalates [Cs(MeCN)(2)}Mes(3)MF}](2) . 2MeCN([1](2) . 6MeCN, M = Ga; [2](2) . 6MeCN, M = In). Ga(CH(2)Ph)(3) gives with CsF under the same conditions the salt [Cs(PhCH(2))(3)GaF}](2) . 2MeCN ([3](2) . 2MeCN). The treatment of 1 equiv CsF with 2 equiv of GaMes(3) does not lead to Cs[Mes(3)GaFGaMes(3)] but to [1](2) . 6MeCN and the adduct [Mes(3)Ga(MeCN)] (4). [1](2) . 6MeCN-4 have been characterized by NMR, IR, and MS techniques as well as by X-ray analyses. [1](2) . 6MeCN and [2](2) . 6MeCN are solvated ion pairs in acetonitrile, while [3](2) . 2MeCN shows a monomer-dimer equilibrium. According to the X-ray structure determinations, [1](2) . 6MeCN and [2](2) . 6MeCN are isostructural and contain Cs-F four-membered rings. The fluorine centers at the rings are bound to the metallane groups. Each cesium cation is coordinated by two molecules of acetonitrile and by one mesityl group in a eta(3)-fashion. The basic structural feature of [3](2) . 2MeCN is also a Cs-F four-membered ring; however, the cations in [3](2) . 2MeCN are surrounded by three phenyl groups of the benzyl substituents. The three eta(6)-bound phenyl rings are contributed from two different metallane units. 4 possesses a distorted tetrahedral coordination sphere with a low pyramidalization of the Ga center (angular sum: 355 degrees).
