1,1,3,3-Tetra-tert-butyl-2,2-diisopropyl-4,4-diphenyl­cyclo­tetra­silane

The molecule in the structure of the title compound, C(34)H(60)Si(4), lies on a twofold rotation axis that passes through the two Si atoms, resulting in a planar cyclo­tetra­silane ring. The dihedral angle between the cyclo­tetra­silane ring and the phenyl ring is 68.20 (5)°. The Si—Si bonds [2.4404...

description The molecule in the structure of the title compound, C(34)H(60)Si(4), lies on a twofold rotation axis that passes through the two Si atoms, resulting in a planar cyclo­tetra­silane ring. The dihedral angle between the cyclo­tetra­silane ring and the phenyl ring is 68.20 (5)°. The Si—Si bonds [2.4404 (8) and 2.4576 (8) Å] are longer than a standard Si—Si bond (2.34 Å) and the C—Si—C bond angle [97.07 (14)°] of the phenyl-substituted Si atom is smaller than the tetra­hedral bond angle (109.5°). These long bonds and small bond angle are favorable for reducing the steric hindrance among the bulky substituents.
