The following compounds have been prepared and characterized by crysta l structure analyses: Two modifications of nitrido-bis(diphenylphosphi nato-O,O')]boronium(1+) triiodide (A and B): A (monoclinic, P2(1)/c; a = 1908.8, b = 1652.7, and c = 1719.4 pm; beta = 109.54 degrees; Z = 4 ; R = 10.3%) and B (triclinic, <P(1)over bar>, a = 981.8, b = 1148.9, and c = 2353.7 pm; alpha = 80,91 degrees, beta = 81.09 degrees, gamma = 74.58 degrees, Z = 2, wR = 7.4%). itrido-bis(diphenylphosphinato-O,O ')]aluminium(1+) triiodide (C) and -imido-bis(diphenylphosphinato-O,O' )]aluminium(1+) bis(hydrogenphosphate) dioxane adduct (D): C (monoclin ic, P2(1)/n, a = 1332.4, b = 4087.6, and c = 1368.1 pm; beta = 93.17 d egrees; Z = 4; R = 10.4%) and D (orthorhombic, Pc2(1)b, a = 1798.7, b = 2151.1, and c = 1948.7 pm; Z = 4; R = 12,8%). Two modifications of - nitrido-bis(diphenylphosphinato-O,O']stannium(1+) perchlorate (E and F ): E (triclinic, <P(1)over bar>, a = 1468.7, b = 1480.2, and c = 1629. 8 pm; alpha = 99.75 degrees, beta = 90.77 degrees, and gamma = 92,65 d egrees, Z = 2, wR = 6,0%) and F (hexagonal, a = 1224 and c = 2110 pm). -nitrido-bis(diethylphosphinato-O,O')]boronium(1+) triiodide has been characterized by IR, FIR, H-1- and P-31 NMR, as well as by mass spect ra.
