Abstract
The phosphorane iminato complexes have been obtained as white
crystalline powders at reacting Me3SiNPCl3 with BCl3, and BBr3,
respectively. Crystallization from CH2Cl2 yields colourless
crystals which have been characterized by single crystal X-ray
diffraction analyses. [Cl2BNPCl2NPCl3](2) (1) crystallizes in
space group P 2(1)/n with a = 961.5(1), b = 830.8(1), c =
1517.0(2) pm, beta = 107.32(1)degrees, Z = 2, R-1 = 0.0479. The
molecule is centrosymmetric, and shows a square planar B2N2
four-membered ring with B-N distances of 154.3 pm.
[Br2BNPCl3](2) (2) crystallizes in space group Cmca with a =
1334,93(8), b = 1189.55(7), c = 1026.42(6) pin, Z = 4, R-1 =
0.0436. The compound forms dimeric molecules with point
symmetry C-2h, The characteristic Feature is a planar square
B2N2 four-membered ring with B-N distances of 155.4 pm. The
compounds have been characterized by NMR-, IR-, and MS-
spectroscopy.
