Silicones interactions

For a theoretical consideration of the metal-silicon interaction in silylene complexes, the fragment orbital description proves to be very useful [148], This approach has been extensively used in the organometallic chemistry of carbon and allows a basic understanding of the interrelations also by means of a qualitative description.

The comparison between iron and manganese complexes, despite their electronic and geometrical resemblances, is difficult because of the highly specific hydrogen-silicon interactions in the case of the manganese complexes. The difference in stereochemistry can certainly be attributed to these interactions in the manganese complex.

Low-energy boron bombardment of silicon has been simulated at room temperature by MD. Tersoff potential T3 was used in the simulation and smoothly linked up with the universal potential. The boron-silicon interaction was simulated according to Tersoff potential for SiC but modified to account for the B-Si interaction. Silicon crystal (Si-c) in the (001) direction, with (2x1) surface reconstruction, was bombarded with boron at 200 and 500 eV. Reasonably good statistics are obtained with 1000 impact points uniformly distributed over a representative surface area. The simulation size was 16x 16x 14 unit cells. Periodic boundary conditions were applied laterally. The temperature was kept at 300 K with a thermal bath applied to the more external cells in the crystal except the top surface. In these conditions the crystal was relaxed during 19 ps. In order to avoid direct channeling, the incidence was inclined 7° out of the normal, as usual in experiments, with random azimuthal direction.

Due to the strong carbon-silicon interactions which are documented by the extremely short C -Si bond, it is anticipated that the ylidic bond (C -P) is lengthened in the solid-state structure 3 (Table 3). In the calculation there is only a slight shortening of the C -Si bond in 3 ,ic. (183.7 pm) as compared to loic. (184.8 pm) and so after all the lengthening effect of the Ci-P bond is not... 

The dependence of the calculated enthalpy of solution of chlorine is comparable to the enthalpy of mixing of Ni-Si melts (Fig. 4) [9]. The extreme value of both dependencies is xsi = 0.375. The negative values of the enthalpy of mixing indicate considerable interactions between nickel and silicon. These interactions should be correlated with chlorine solubility in the nickel silicides. Both findings could point to the already frequently assumed strong metal-silicon interactions in transition metal silicides [10]. 

Much research work has been devoted to the direct process for alkoxysilanes, based on silicon interaction with alcohol (Eq. 3) [1-5].
