| Abstract: | Structure of Pentaphenyldisiloxane Pentaphenyldisiloxane was obtained by reaction of triphenylsilanol with diphenylchlorosilane and triethylamine. The compound crystallizes as colourless triclinic platelets (P1 ; a = 1069.6; b = 1389.6; c = 925.5 pm; α = 106.17; β = 9239; γ = 95.93°; Z = 2). The X-ray structure analysis shows a bent configuration of the molecule with Si? ;O? Si = 163.3°. The structure of the molecules is discussed in relation to the structures of 1,1,3,3-tetraphenyldisiloxane, 1,3-dimethyl-1,1,3,3-tetraphenyldisiloxane and pentaphenylmethyldisiloxane. |
