Tris(triphenylphosphoraneiminato)borane, B(NPPh 3 ) 3 B(NPPh 3 ) 3 has been prepared by the reaction of BF 3 · OEt 2 with LiNPPh 3 in toluene/tetrahydrofuran. Moisture sensitive single crystals of B(NPPh 3 ) 3 · 0.5 C 7 H 8 were obtained and characterized by NMR and IR spectroscopy as well as by a crystal structure determination. Space group P2 1 /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)°, R 1 = 0.070. The compound forms monomeric molecules with a planar BN 3 skeleton and BN bond lengths of 144.7 pm on average.
