| Abstract: | Tris(triphenylphosphoraneiminato)borane, B(NPPh3)3 B(NPPh3)3 has been prepared by the reaction of BF3 · OEt2 with LiNPPh3 in toluene/tetrahydrofuran. Moisture sensitive single crystals of B(NPPh3)3 · 0.5 C7H8 were obtained and characterized by NMR and IR spectroscopy as well as by a crystal structure determination. Space group P21/n, Z = 4, lattice dimensions at –70 °C; a = 2147.8(3), b = 978.5(2), c = 2423.8(2) pm, β = 114.11(1)°, R1 = 0.070. The compound forms monomeric molecules with a planar BN3 skeleton and BN bond lengths of 144.7 pm on average. |
