Synthesis and Crystal Structure of 10-Phenyl-1,7-dithia-4-oxa-10-aza-12-crown-4

The crystal structure of the title compound C₁₄H₂₁ONS₂ was determined by means of X-ray diffraction method.Its crystallog raphic data are as follows:M_r=283.46,it is a monoclinic crystal system,the space group P2₁/n,a=1.273 7(3)nm,b=1.510 9(5)nm,c=0.798 0(6)nm,=107.17(3)°,V=1.467 4 nm³,Z=4,D_c=1.283 g·cm^-3,(MoK)=3.370 cm^-1,F(000)=608,R₁=0.079,R_w=0.076 for 1.689 observed reflections with I≥6(I).Both the phenyl and hetero cyclic rings in the title compound are distorted to form a conjugate system.
