Cover illustration: The molecule 6-(1-methylethyl)-12-phenyl-5,6,7,12-tetrahydrodibenz[c,f][1,5]azasilocine, C23H25NSi, is an example of a highly coordinated hydrosilane. The silicon atom adopts a distorted trigonal-bipyramidal geometry with a short transannular SiN distance of 2.6294 (18) Å. Unusually, the Si-H hydrogen atom occupies an axial rather than an equatorial site. See Goto, Fukushima & Kawashima [Acta Cryst. (2010). E66, o20].
