The structure of poly(diethylsilylenemethylene) (PDESM), poly(di-n-butylsilylenemethylene) (PDBSM), poly(di-n-pentylsilylenemethylene) (PDPeSM) and poly(di-n-hexylsilylenemethylene) (PDHSM) have been studied using X-ray and electron diffraction methods. The structure of poly(di-n-propylsilylenemethylene) (PDPrSM) has been studied and reported in a separate paper. PDBSM, PDPrSM, PDPeSM and PDHSM all...
The structure of poly(di-n-propylsilylenemethylene) (PDPrSM) has been studied by X-ray diffraction, electron diffraction and molecular modeling. The fiber X-ray data and the electron diffraction pattern of single crystals show that PDPrSM has triclinic symmetry with unit cell parameters a=10.52 A ̊, b=8.66 A ̊, c=4.86 A ̊, α=78.4°, β=100.0° and γ=98.2°. The fiber repeat, 4.86Å, indicates an all-gauche...
