organic compounds
The structure of the title compound, C12H12P+·Br−, is composed of discrete cations and anions, which are both located on a crystallographic mirror plane. The angle between the two phenyl rings is 69.18 (11)°. The crystal packing is stabilized by P—HBr hydrogen bonds.
organic compounds
The title compound, C8H19OP, is the oxidation product of tBu2PH. The molecule is located on a crystallographic mirror plane. As a result, there is just one half-molecule in the asymmetric unit.
organic compounds
The structure of the title compound, C14H16P+·I-, has been reported previously by Staples, Carlson, Wang & Fackler [Acta Cryst. (1995), C51, 498-500] in the space group P6522 without any information about the determination of the absolute structure. We present here a redetermination of this structure from new intensity data in the space group P6122 with the direction of the polar axis unequivocally determined for this particular crystal. Both the cation and anion are located on twofold rotation axes.
