| Abstract: | 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 P21/c with a = 5.7002(5), b = 12.186(1), c = 14.312(1) , b = 92.503(2), C24H24N2O2, Mr = 372.46, V = 993.16(15) 3, Z = 2, m = 0.080 mm-1, Dc = 1.245 g/cm3 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 CH…p as well as face-to-face p…p inter- actions, |
