Formation of organosilicon compounds. 47. The crystal land molecular structure of 1,3,5,7-tetramethyl-tetrasila-adamantan1,3,5,7- Tetramethyl-tetrasila-adamantan, Si4C10H24, is a pyrolysis product of Si(CH3)4. It crystallizes in the monoclinic space group P21/c with a = 8.859 Å, b = 9.844 Å, c = 18.316 Å, β = 91.04°, Z = 4. The molecule exhibits Td-symmetry within the experimental error. The mean bond lengths Si—C are 1.889 Å and 1.866 Å for the Si—CH3 and Si—CH2 bonds respectively.
Notes:
Das bei der Pyrolyse von Si(CH3)4 gebildete 1,3,5,7- Tetramethyltetrasila-adamantan Si4C10H24 Kristallisiert monoklin in der Raumgruppe P21/c mit a = 8,859 Å, b = 9,844 Å, c = 18,316 Å, β = 91,04°, Z = 4. Das Molekül besitzt innerhalb der Fehlergrenzen Td-Symmetrie. Die mittleren Bindungslängen Si—C betragen 1,889 Å bzw. 1,866 Å für Bindungen Si—CH3 bzw. Si—CH2.
