 Title    Synthesen und Kristallstrukturen von [PPh 3 Me]N0 2 und [PPh 3 Me]HC0 2 H 2 0 Syntheses and Crystal Structures of [PPh 3 Me]N0 2 and [PPh 3 Me]HC0 2 H 2 0  
 Abstract    Triphenylmethylphosphonium nitrite and formate have been prepared by the reaction of [PPh,Me]I with silver nitrite, and lead formate, respectively, in aqueous solutions. [PPh 3 Me]N0 2 (1) forms pale yellow crystals, and [PPh 3 Me]HC0 2 H 2 0 (2) forms white crystals. Both com-pounds are soluble in water, ethanol, and dichloromethane. In moist air 2 is hydrated to yield [PPh 3 Me]HC0 2 -2H 2 0 (3). The compounds were characterized by their IR spectra. 1 and 2 also by X-ray crystal structure determinations. [PPh 3 Me]NO-> (1): space group P2,/«, Z = 4, 2088 independent observed reflexions, R = 0.062. Lattice dimensions (20 °C): a = 914.7(3), b = 1887.5(9), c = 1080.0(4) pm, ß = 110.29(3)°. The compound consists of PPh,Me + ions and NO-," anions with bond lengths of 114.2(6) pm and a bond angle of 124.1(7)°. [PPh 3 Me]HCOi • H^O (2): space group P2,/n, Z = 4, 2973 independent observed reflexions, R = 0.069. Lattice dimensions (-20 °C): a = 931(2), b = 1558(3), c = 1281(2) pm, ß = 105.9(1)°. The compound consists of PPh 3 Me + ions and formate anions which form centrosymmetric dimeric units [HCOvftO]?" through hydrogen bridges of the water molecules. Bond lengths CO 122.4(4) and" 120.9(4) pm. bond angle OCO 129.9(4)°.
