Abstract:
The title compound, C29H37BrSi, was synthesized by the Sonogashira coupling of [(3,5-diethyl-4-ethynylphen-yl)ethyn-yl]triiso-propyl-silane with 4-bromo-1-iodo-benzene. In the structure, the two phenyl rings are nearly parallel to each other with a dihedral angle of 4.27 (4)°. In the crystal, π-π inter-actions between the terminal and central phenyl rings of adjacent mol-ecules link them in the a-axis direction [perpendicular distance = 3.5135 (14); centroid-centroid distance = 3.7393 (11) Å]. In addition, there are weak C-H⋯π inter-actions between the isopropyl H atoms and the phenyl rings of adjacent mol-ecules.
