  Die Tris(triisopropylsilyl)pnikogene: Synthese und Charakterisierung von [E(SiiPr3)3] (E = P, As, Sb)

  摘要：

  The compounds [E((SiPr3)-Pr-i)(3)] (E = P, As, Sb) (1-3) were prepared in high yields by the reaction of (Na/K)(3)E with (Pr3SiCl)-Pr-i in DME. They were characterised by H-1-, C-13-, Si-29- and P-31-NMR spectroscopy, mass spectrometry and single crystal X-ray diffraction. Compound 1, recently obtained in a different way, shows an unusual trigonal planar coordination of the central phosphorus atom. However, 2 and 3, featuring increasing covalence radii of the central atoms, show an increasingly pyramidal structure. 1-3 crystallise isotyp in the cubic spacegroup Pa (3) over bar, the lattice constants are: 1: a = 1860.1(2) pm, 2: a = 1873.6(2) pm, 3. a = 1897.1(2) pm.
