The title complex, [IrH(CO)(PPh3)3](1), reacts with MH3Q (M = Si or Ge when Q = H, F, Cl, Br, or I; M = Si when Q = SiH3 or CH3) to give [IrH2(CO)(PPh3)2(MH2Q)]. The products have been characterised by 1H, 31P, and (where appropriate)19F n.m.r. spectra. Where M = Ge, the predominant isomer contains mutually trans phosphine ligands, whereas when M = Si the predominant (and in some cases the sole) product
GeH3Br have been synthesized by streaming GeH4 over heated AgCl or AgBr, respectively. The new digermanylhalides, Ge2H5Cl and Ge2H5Br, have been prepared by analogous reactions involving Ge2H6 in place of GeH4. Digermanyl bromide has also been synthesized by the direct reaction of Ge2H6 with bromine. Digermanyl iodide has been converted by reaction with the appropriate silver salt to Ge2H5Br and Ge5H5Cl
通过分别在加热的AgCl或AgBr上流过GeH 4来合成GeH 3 Cl和GeH 3 Br 。通过涉及Ge 2 H 6代替GeH 4的类似反应制备了新的二锗烷基卤化物Ge 2 H 5 Cl和Ge 2 H 5 Br 。还通过Ge 2 H 6与溴的直接反应合成了二锗烷基溴。通过与适当的银盐反应已将二锗烷基碘化物转化为Ge 2 H 5 Br和Ge 5 H 5Cl。已经研究了GeH 3 SiH 3的一些反应。

Single vibronic level dispersed fluorescence spectra of jet-cooledHGeBr, DGeBr, HGeI, and DGeI have been obtained by laser excitation of selected bands of the A (1)A(")-X (1)A(') electronic transition. The measured ground state vibrational intervals were assigned and fitted to anharmonicity expressions, which allowed the harmonic frequencies to be determined for both isotopomers. In some cases, lack

is always to give trans-[Ir(CO)H(X)(PEt3)2(MH2Q)]; when M = Si the major (and in most cases the only) product has H trans to Si; when M = Ge the major (and in some cases the only) product has H trans to X. When X = Cl and Q = Br or I, the silyl adducts contain Cl bound to Si and Br or I bound to Ir; when M = Ge, however, the adduct initially formed contains Cl bound to Ir and Br or I bound to Ge, although

been prepared from the appropriate primary and secondary difluorophosphinoamines by reaction with germyl halide and trimethylamine. The compounds are all much more stable than trigermylamine, but decompose at room temperature by elimination of GeH2. Vibrational, photoelectron, n.m.r., and mass spectroscopic data have been recorded, and are interpreted in terms of the probable conformations adopted by
