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)Å, V=4125.63(15)Å3, 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.
