Halogenated polysilane as a pure compound or mixture of compounds each having at least one direct bond Si-Si, whose substituents are halogen and in whose composition the atomic ratio substituent: silicon is at least 1: 1, characterized in that the polysilane of rings and chains with a high proportion of branching points, which is> 1% based on the total product mixture, has a Raman molecular vibration spectrum of I 100 / I 132 <1, where I 100 is the Raman intensity at 100 cm -1 and I 132 is the Raman intensity at 132 cm -1 , and has significant product signals in the chemical shift range of +23 ppm to -13 ppm, -18 ppm to -33 ppm, and -73 ppm to -93 ppm in 29 Si NMR spectra. |
