1,4-Bis[4-(tert-butyl­diphenyl­silyl)buta-1,3-diyn­yl]benzene

The title centrosymmetric mol­ecule, C(46)H(42)Si(2), is composed of a central benzene ring with buta-1,3-diynyl chains at positions 1 and 4. These chains are terminated by tert-butyl­diphenyl­silyl groups, hence the molecule is dumbbell in shape. The mol­ecules are connected via C—H⋯π inter­actions...

Sumario:The title centrosymmetric mol­ecule, C(46)H(42)Si(2), is composed of a central benzene ring with buta-1,3-diynyl chains at positions 1 and 4. These chains are terminated by tert-butyl­diphenyl­silyl groups, hence the molecule is dumbbell in shape. The mol­ecules are connected via C—H⋯π inter­actions in the structure, so forming an undulating two-dimensional network in the bc plane. There is also a weak π–π inter­action involving centrosymmetrically related phenyl rings with a centroid–centroid distance of 3.8359 (11) Å.
