摘要：

(PPh4)2Se6 has been prepared by the reaction of selenium with K2Se2 in dimethylformamide solution in the presence of K3[Mn(CN)6] and PPh4Br, forming black crystal needles. According to the crystal structure determination the compound consists of PPh4+ ions and chainlike hexaselenide ions. Space group P1BAR, Z = 2, 4683 observed unique reflections, R = 0.066. Lattice dimensions at -90-degrees-C: a = 951.0, b = 1094.8, c = 2137.4 pm, alpha = 82.66-degrees, beta = 83.36-degrees, gamma = 89.96-degrees.
