Organometallic compounds of the lanthanides. 64. Synthesis and X-ray crystal structures of dimethylgermyl bis(tetramethylcyclopentadienyl) halide and alkyl derivatives of the lanthanides

Metathesis of Me2GeCl2 or Me2SnCl2 with 2 equiv of LiC5Me4H affords Me2Ge(C5Me4H)2 (1) and Me2Sn(C5Me4H)2 (2), respectively. The subsequent deprotonation of 1 with MeLi yields only the desired dilithium salt Me2Ge(C5Me4Li)2 (3) whereas 2 forms Me4Sn and two LiC5Me4H. The trichlorides of neodymium, samarium, holmium, and lutetium react with the dilithium salt 3 with the formation of Me2Ge(C5Me4)2LnCl 2Li(THF)2 (Ln = Nd (4), Sm (5), Ho (6), Lu (7)). The reaction of 4 and 6 with LiCH(SiMe3)2 produces Me2Ge(C5Me4)2LnCH(SiMe 3)2 (Ln = Nd (8), Ho (9)). The new compounds have been characterized by elemental analysis, mass and NMR spectra, as well as X-ray structural analysis of 5, 7, and 9. The halides 5 and 7 crystallize in the monoclinic space group P21/c (No. 14) with a = 9.7284 (9), b = 19.397 (1), c = 16.610 (2) ?, β = 98.963 (9)°; Z = 4 or a = 9.578 (3), b = 19.218 (4), c = 16.525 (4) ?, β = 99.73 (2)°; Z = 4, respectively. Least-squares refinement led to a final R value of 0.020 (Fo > 4σ(Fo)) for 5554 independent reflections for 5 or of 0.028 (Fo > 3σ(Fo)) for 5822 independent reflections for 7. Compound 9 crystallizes in the monoclinic space group P21/m (No. 11) with a = 9.2621 (8), b = 14.216 (2), c = 11.839 (2) ?, β = 107.79 (1)°, Z = 2, and R = 0.023 (Fo > 4σ(Fo)) for 2954 reflections. The structure of 9 shows a short Ho-C (methyl) contact of 2.774 (4) ?.

Molecular Oligogermanes and Related Compounds: Structure, Optical and Semiconductor Properties

The optical (UV/Vis absorbance, fluorescence in the solid state and in solution) and semiconducting properties of a number of di- and trigermanes as well as related silicon- and tin-containing germanes, 1–6 ((p-Tol)3GeGeMe3 (1), Ph3SnGe(SiMe3)3 (2), (C6F5)3GeGePh3 (3), (p-Tol)3GeSiMe2SiMe3 (4), (p-Tol)3GeGeMe2Ge(p-Tol)3 (5), (p-Tol)3GeSiMe2SiMe2Ge(p-Tol)3 (6)) were investigated. Molecular structures of 5 and 6 were studied by X-ray diffraction analysis. All compounds displayed luminescence properties. In addition, a band gap (of about 3.3 eV) was measured for compounds 1–6 showing that those molecules display semiconductor properties.

Transient and Matrix Ultraviolet Absorption Spectra of Dimethylgermylene (Dimethylgermanediyl)

Reactivity, absorption and emission of dimethylgermylene photo-generated from dodecamethylcyclohexagermane

The UV photolysis of dodecamethylcyclohexagermane (1) in cyclohexane at room temperature proceeds readily with loss of dimethylgermylene species to give two of the lower homologs, decamethylcyclopentagermane (2) and octamethylcyclotetragermane (3).The photochemically generated dimethylgermylene species reacts with 2,3-dimethylbuta-1.3-diene or CCl4 to give 1,1,3,4,-tetramethyl-1-germacyclopent-3-ene or trichloromethyldimethylchlorogermane, respectiively.The transient absorption of 1 in cyclohexane at 450 nm obtained by laser flash-photolysis is due to dimethylgermylene.The reaction rates of dimethylgermylene with some substances are examined.In 3-methylpentane glass dimethylgermylene shows an absorption band at 430 nm and a fluorescence peak at 650 nm.The photo-generated germylene appears to be the singlet ground state.

Oligogermanes containing only electron-withdrawing substituents: Synthesis and properties

A series of germanes Ar3GeX, containing electron-withdrawing substituents [Ar = p-FC6H4, 1a-d, 1a (X = Cl), 1b (X = Br), 1c (X = H), 1d (X = NMe2); p-F3CC6H4, 2a-d, 2a (X = Cl), 2b (X = Br), 2c (X = H), 2d (X = NMe2)], was synthesized and used to prepare symmetrical digermanes Ar3Ge-GeAr3, (p-FC6H4)3GeGe(C6H4F-p)3 (3), and (p-F3CC6H4)3GeGe(C6H4CF3-p)3 (4) and trigermane [(pF3CC6H4)3Ge]2Ge(C6F5)2 (5) by hydrogermolysis reaction. The properties of all compounds were investigated by multinuclear NMR and for oligogermanes by UV/vis and fluorescence spectroscopy, as well as by electrochemical methods. In addition, the molecular structures of 1a, 1b, 2b, 2c, and 3-5 were studied by X-ray diffraction analysis. Compound 5 showed a significantly shifted UV/visible absorption to the red field in comparison with previously described derivatives.

Organotrichlorogermane synthesis by the reaction of elemental germanium, tetrachlorogermane and organic chloride via dichlorogermylene intermediate

Organotrichlorogermanes were synthesized by the reaction of elemental germanium, tetrachlorogermane and organic chlorides, methyl, propyl, isopropyl and allyl chlorides. Dichlorogermylene formed by the reaction of elemental germanium with tetrachlorogermane was the reaction intermediate, which was inserted into the carbon-chlorine bond of the organic chloride to give organotrichlorogermane. When isopropyl or allyl chloride was used as an organic chloride, organotrichlorogermane was formed also in the absence of tetrachlorogermane. These chlorides were converted to hydrogen chloride, which subsequently reacted with elemental germanium to give the dichlorogermylene intermediate. The reaction of elemental germanium, tetrachlorogermane and organic chlorides provides a simple and easy method for synthesizing organotrichlorogermanes, and all the raw materials are easily available.

The synthesis, reactivity, and characterization of the digermylplatinum(II) linear complexes (ClMe2Ge)2Pt(PPh3)2 (1) and (ClMe2Ge)2Pt(diphos) (2) and cyclic complexes (diphos)PtGe-(Me2)EGeMe2 [E = S (3), -NPh (4), (η5-C5H4)Fe(η5-C 5H4) (5), O (6)] are reported. The chemistry of 2-6 is illustrated through their reactions with phenylacetylene and N-methyltriazolinedione. Complexes 3 and 6 give double germylation of these unsaturated systems, while 2, by reaction with triazolinedione, gives the monogermylated complex Me2-(Cl)GePt(Cl)diphos and the dimer of the germylated heterocycle Me2GeNC(O)N(Me)C(O)N.
