The crystal is of triclinic, space group P?with unit cell constants: a = 6.0740(1), b = 10.3250(1), c = 19.779(2) , ?= 76.740(1), = 87.110(1), = 74.920(1), C24H24Cl2N2O2S, Mr = 475.41, Z = 2, V = 1165.7(3) ?, Dc = 1.354 g/cm3, (MoK) = 0.71073, = 0.392 mm-1, F(000) = 496, the final R = 0.0324 and wR = 0.0819 for 3102 observed reflections (I > 2(I)). X-ray analysis reveals that the two morpholinyl groups are located at the -position of thiophene, and the two p-chlorophenyl groups at the -position. Therefore, the title compound is a new symmetric thiophene derivative.展开更多

The crystal is triclinic, space group Pī, with unit cell constants a=6.074(1), b=10.325(1), c=19.779(2)? a=76.74(1), b=87.11(1), g=74.92(1), Z=2, V=1165.7(3)?, Dc=1.354g穋m-3, m (MoKa)=0.392mm-1, F(000)=496, R=0.0324, Rw=0.0458 for 3102 observed reflections(I>2s(I)). X-ray analysis reveals that interatomic distances for C(7)C(19) and C(8)C(20) are 1.368(2) and 1.365(2)? respectively, which shows that they are C=C double bonds. The atoms of C(7), C(8), C(19), C(20) and S form a thiophene ring and the morpholine adopts chair conformation.展开更多
