Coordinative interactions in chelated complexes of silicon, part III. Crystal and molecular structure of 1-trichlorosilyl-1,2,3,4-tetrahydro-1,10-phenanthroline
- The crystal structure of C12H11N2SiCl3 (monoclinic, P21/m, Z = 2, with a: 9.284(4), b: 7.226(2), c: 10.832(5) Å, β = 115.14(3)°) was refined to R(F) =0.035 from 1228 independent reflections. A trigonal bipyramidal, pentacoordinate silicon is observed. The chelated complex shows two different Si−N bonds, a coordinative bond (1.984(2) Å) between 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.
