The crystal structures of Me3SNP(c-C6H11)(3) (1) and (Me3SiNPPh2)(2)CH2 (2)
are determined by X-ray diffraction at single crystals. In both compounds
the PN distances correspond to double bonds, the SiN distances to single bo
nds. With 149.8 degrees the SiNP bond angle in 1 is noticeably large, while
it is only 138.5 degrees in 2, which shows C-2 symmetry. 1: Space group P2
(1)/n, Z = 4, lattice dimensions at -70 degrees C: a = 1143.0(1), b = 1743.
0(2), c = 1152.5(1) pm, beta = 90.42(1)degrees; R = 0.0677. 2: Space group
I4(1)/a, Z = 8, lattice dimensions at -60 degrees C: a = b = 1959.7(1), c =
1695.8(1) pm, R = 0.0433.
