title: 6-(1-Methyl-ethyl)-12-phenyl-5,6,7,12-tetra-hydro-dibenz[c,f][1,5]aza-silocine.
abstract: The title compound, C(23)H(25)NSi, has an eight-membered silicon-containing heterocyclic ring with an intra-molecular N⋯Si close contact, the transannular distance of which is 2.6294 (18) Å. The resulting geometry about the Si atom is distorted trigonal-bypyramidal, with the N and H atoms occupying apical sites. The dihedral angle between the aromatic rings fused to the eight-membered ring is 63.27 (7)°.
