摘　　要：2-甲基-8-羟基喹啉和二溴丁烷在正丁基锂的存在下反应,生成标题化合物(C24H24N2O2, Mr = 372.46)。X-射线单晶结构分析表明此晶体属于单斜晶系,空间群P21/c, a = 5.7002(5), b = 12.186(1), c = 14.312(1) , b = 92.503(2), V = 993.2(2) 3, Z = 2, m = 0.080 mm-1, Dc = 1.245 g/cm3, F(000) = 396, R = 0.0505, wR = 0.0705. 结果表明,该化合物的2个配位端基2-甲基-8-羟基-喹啉基处于间隔基团-(CH2)4-的两侧,整个分子呈现中心对称的反式构象。此外,通过分子间的p…p 堆积作用和 CH…p 作用,使分子堆积成三维网络结构。The title compound was synthesized by the reaction of 8-hydroxyquinoline and 1,4-dibromobutane in the presence of n-butyllithium. It crystallizes in monoclinic, space group P2(1)/c with a=5.7002(5), b=12.186(1), c=14.312(1) Angstrom, beta=92.503(2)degrees, C24H24N2O2, M-r=372.46, V=993.16(15) Angstrom(3), Z=2, mu=0.080 mm(-1), D-c=1.245 g/cm(3) and F(000)=396. The final R=0.0505 for 1498 observed reflections. The molecular structure with two terminal groups MOQ being symmetrically located on both sides of the spacer -(CH2)(4-) presents trans-conformation, and these molecules (as building blocks) can be assembled into a 3-dimensional network by weak intermolecular edge-to-face C-H...pi as well as face-to-face pi...pi interactions.
