It crystallizes in monoclinic system, space group P21/n with a = 5.55916(10), b = 17.4870(3), c = 7.70677(13) A, V = 744.89(2) A3, Z= 4, Dc= 1.321 g/cm3, Mr = 148.15, F(000) = 312, and/t μ=0.764 mm-1. A total of 2661 reflections with 1447 unique ones (Rint = 0.0137) were collected, in which 1447 were observed (I〉2σ(/)). There were two C9H802 molecules in an asymmetric unit. The structural unit was a dimer formed by the hydrogen bonding of the oxygen atom of carbonyl group and the hydrogen atom of hydroxyl group. A 3D layer structure was formed through hydrogen bonds and Van der Walls' forces.展开更多

It crystallizes in triclinic, space group P1- with a = 8.9438(4), b = 11.6065(5), c = 14.2215(6)A, α = 112.566(1), β = 92.324(2), γ = 102.91(1)°, V= 1315.65(10) A^3, Z = 2, Dc = 1.344 g/cm^3,μ(MoKa) = 0.282 mm^-1, λ = 0.71073 A, F(000) = 552, the final R = 0.0587 and wR = 0.1578 for 5071 observed reflections (I 〉 2σ(I)). X-ray analysis reveals that the product is a thermodynamically stable trans isomer. Intra- and intermolecular C( 12)-H(12)…O(1) and C(28)-H(28)...O(1)# 1 hydrogen bonds were observed in the title compound.展开更多
