The complex compound of [Na(OPPh3)4]PF(6) formula was obtained in the reaction of triphenylphosphine oxide (OPPhs) with sodium hexafluorophosphate (NaPFg) in dichloromethane (CH(2)Cl(2). The slow crystallization at room temperature produced crystals suitable for X-ray analysis. Crystals are triclinic, space group P1 with a = 12.035(3), b= 14.268(3), c = 19.397(4) A, Alfa = 72.72(2), beta = 89.14(2), gamma = 88.29(2)°, V = 3178.9(12 A3 and Z = 2 at 100 K. The sodium cation is surrounded by four oxygen atoms of OPPh(3) ligands in a tetrahedral fashion. The slight difference of Na-O distances (2.207(2)-2.239(2) A) as well as remarkable difference of P-O-Na angles (137.37(7)-172.55(9)°) found in [Na(OPPh3)4J+ cation are explained by formation of intramolecular C-H.. .O interactions as well as intermolecular interactions of C-H.. .F type between phenyl rings and fluorins of PF-(6).
