Abstract
The title compound, C23H24O4Si, was synthesized by photo-induced reactions and characterized by single-crystal X-ray diffraction. The compound crystallizes in the orthorhombic space group Pbca, with a=9.7299(2), b=19.6064(4), c=21.6264(5)A, V=4125.63(15)A3, Z=8 and Dx 1.264 g cm-3. The dihedral angle between the cyclobutene and the attached benzene ring is 38.04(13)°. The molecules are linked into an infinite chain along the a-axis. The crystal structure is stabilized by weak C-H…O and C-H…π interactions.
通过光诱导反应合成了标题化合物C23H24O4Si，并用单晶x射线衍射对其进行了表征。化合物在正交空间群Pbca中结晶，a=9.7299(2)， b=19.6064(4)， c=21.6264(5) a, V=4125.63(15)A3, Z=8, Dx为1.264 g cm-3。环丁烯与所附苯环的二面角为38.04(13)°。分子沿着a轴连接成一条无限链。弱的C-H…O和C-H…π相互作用稳定了晶体结构。
