Fourteen new triphenylgermanium derivatives of alkynyl or alkenyl phosphonic acid were synthesized by the reaction of corresponding triphenylgermanium chloride with alkynyl or alkenyl phosphates. All compounds were ch...Fourteen new triphenylgermanium derivatives of alkynyl or alkenyl phosphonic acid were synthesized by the reaction of corresponding triphenylgermanium chloride with alkynyl or alkenyl phosphates. All compounds were characterized by elemental analysis, IR, 1H NMR and MS. The results showed that bis(triphenylgermanium) alkynyl or alkenyl phosphonates are both four- and five-coordinated germanium and triphenylgermanium alkynyl or alkenyl phosphonates are five-coordinated germanium.展开更多

The crystal is triclinic, space group P-1 with parameters: a=9.7753(5), b=11.5773(5), c=13.5059(6) ?, α=104.185(1),β= 95.971(1), γ =96.727(1)°, V=1457.63(12) ?3, Z=2, Mr=574.13, Dc=1.308 g/cm3, λ=0.71073 ?, μ = 1.139mm-1, and F(000)=596. The structure was solved by direct methods. The structure was refined to R=0.0257, wR=0.0705 for 5080 observed reflections with I >2σ(I).The result of structure analysis indicates that atom Ge is sp3 hydridized because the arrangement of the four carbon atoms bonded to it is a distorted tetrahedron. The geometry of the three phenyl groups linking with the Ge atom looks like a propeller form.展开更多
