Crystal Structure of a Novel Diyne, 1,4-Bis(4-((Z)-1-phenyl-2-(trimethylsilyl)vinyl)phenyl)buta-1,3-diyne

Abstract

The crystal of the title compound, C38H38Si2, belongs to space group P1 with cell dimensions of a = 8.6324(6), b = 6.8543(5), c = 27.610(2)Å, a = 89.982(4), b = 89.783(4), and g = 89.990(5)˚. The final R value is 0.057. The central 1,4diphenylbuta-1,3-diyne moiety takes a linear and planar structure. The trimethylsilyl and the terminal phenyl groups are located on opposite sides with respect to the central planar part.
