Crystal structure of ({4-[(4-bromo­phen­yl)ethyn­yl]-3,5-di­ethyl­phen­yl}ethyn­yl)triiso­propyl­silane

The title compound, C(29)H(37)BrSi, was synthesized by the Sonogashira coupling of [(3,5-diethyl-4-ethynylphen­yl)ethyn­yl]triiso­propyl­silane with 4-bromo-1-iodo­benzene. 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 inter­actions between the terminal and central phenyl rings of adjacent mol­ecules 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 inter­actions between the isopropyl H atoms and the phenyl rings of adjacent mol­ecules.
