 Title    Coordinative Interactions in Chelated Complexes of Silicon, Part HI Crystal and Molecular Structure of l-Trichlorosilyl-l,2,3,4-tetrahydro-l,10-phenanthroline  
 Abstract    The crystal structure of Ci2HiiN2SiCl3 (monoclinic, P2i/m, Z = 2, with a: 9.284(4), b: 7.226(2), c: 10.832(5) Ä, ß = 115.14(3)°) was refined to R(F) -0.035 from 1228 inde-pendent reflections. A trigonal bipyramidal, pentacoordinate silicon is observed. The chelated complex shows two different Si-N bonds, a coordinative bond (1.984(2) A) be-tween Si and N on the axial position and a Si-N single bond (1.737(3) A, equatorial plane), introduced by chemical reaction. The coordinative bond is 14.2% longer than the Si-N single bond. The lengthening of the coordinative bond in the present case is compared with distances in other extracoordinated silicon compounds.
