摘要 合成了一个新的具有刚性间隔体的双三联吡啶配体—4,4′-二(2,2′∶6′,2″-三联吡啶-4′-酚羟甲基)联苯(L1)。核磁氢谱及X射-线单晶结构表征表明:配体L1晶体属于三斜晶系,P-1空间群,晶胞参数a=1.3247(6)nm,b=1.3704(5)nm,c=1.3892(7)nm,α=103.870°,β=97.650(15)°,δ=115.750(12)°,V=2 122.5(15)3,Z=2,F(000)=868,R=0.0890,wR=0.1856。在分子间氢键作用和范德华力作用下形成三维堆积网状结构。 A novel ligand 4, 4′-bis ( 2,2′: 6′,2″-terpyridine-4′-phenolicmethylene) biphenyl ( L^1 ) containing a rigid spacer was synthesized and characterized by ^1H-NMR and single crystal X-ray diffraction. The tide complex belongs to monoclinic system with space group a = 1. 3247(6) nm,b = 13. 704(5) nm,c = 13.892(7) nm,α = 103. 870°, β = 97. 650 ( 15 ) °,δ = 115. 750 ( 12 )°, V = 2122.5 ( 15 ) A^3, Z = 2, F (000) = 868, R = 0. 0890, wR = 0. 1856. Furthermore, a three-dimensional framework is formed by intramolecule hydrogen bonds and Van der Waals force
