Dinucleating macrocyclic Schiff bases derived from the condensation of thiophene-2,5-dicarbaldehyde and a number of α,ω-alkanediamines are reported together with their barium and silver complexes. The crystal structure of the macrocycle derived from 3-oxapentane-1,5-diamine, 6,19-dioxa-27,28-dithia-3,9,16,22-tetra-azatricyclo[22.2.1.1 11,14]octacosa-2,9,11,13,15,22,24,26-octaene, has been determined
据报道,由噻吩-2,5-二甲醛和许多α,ω-链烷二胺的缩合衍生而来的成核大环席夫碱及其钡和银配合物。衍生自3-oxapentane-1,5-diamine,6,19-dioxa-27,28-dithia-3,9,16,22-tetra-azatricyclo [22.2.1.1 11,14 ] octacosa的大环的晶体结构已确定-2,9,11,13,15,22,24,26-辛烯。晶体是空间群P 2 1 2 1 2 1的正交晶体,其中a = 25.820(13),b = 14.275(6),c = 5.938(2)Å和Z = 4。1629 I /σ的独立反射(我)> 3.0得出R = 0.0442。衍生自3,6-dioxaoctane-1,8-diamine,[6,9,22,25-tetraoxa-33,34-dithia-3,12,19,28-四氮杂三环[28.2.1.1 14,17 ]
