摘      要:The title complex,6,6-(3,3,5,5-tetra-tert-butylbiphenyl-2,2-diyl)bis(oxy)di-di-benzo[d,f]-[1,3,2] dioxaphosphepine(C52H56O6P2·C6H14,Mr = 881.99),was synthesized,and the structure was determined by X-ray single-crystal *** crystal belongs to the orthor-hombic system,space group Pbca,with a = 11.8400(13),b = 25.381(3),c = 34.243(4) ,V = 10290(2)(A°)^3,Z = 8,Dc = 1.139 g/cm^3,μ = 0.131 mm^-1,T = 152(2) K,F(000) = 3768,the final R = 0.0773 and wR = 0.1820 for 9721 observed reflections with I 〉 2σ(I).The neighboring two molecules form a dimmer by face-to-face π…π interactions.
