procedures for preparing digermane were studied experimentally. The plasma chemical procedure in corona discharge is the most promising. The kinetic curves of the digermane synthesis in corona discharge were obtained experimentally, and the activation energy was calculated. The removal of digermane from the reaction zone using a flow-through reactor with partial condensation of digermane in the first step

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

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

The vibrational spectra of the three (amino)monohalogenosilanes show dramitic changes on solidification, but those of the (amino)dichlorosilane are very similar in all three phases. These differences are discussed in the light of the formation of dimers in the crystalline solid of SiH2Cl(NMe2), and the presence of discrete monomers in the crystal of SiHCl2(NMe2). The n.m.r. spectra of the compounds
Abstract A previous measurement of the rotational spectra of SiH3D, SiH2D2, and SiHD3 has been extended in frequency region to determine rotational constants and quartic centrifugal distortion constants. Similar observations have been performed on GeH3D, GeH2D2, and GeHD3, consisting of five, three, and three Ge isotopes, respectively, and also on SnH3D, SnH2D2, and SnHD3 with seven, three, and three
摘要 先前对 SiH3D、SiH2D2 和 SiHD3 旋转光谱的测量已在频率范围内扩展,以确定旋转常数和四次离心畸变常数。对分别由五个、三个和三个 Ge 同位素组成的 GeH3D、GeH2D2 和 GeHD3 以及分别由七个、三个和三个 Sn 同位素组成的 SnH3D、SnH2D2 和 SnHD3 也进行了类似的观察。分析观察到的旋转常数以估计三个分子的平衡核间距离。
