new coordination compounds Zn(SCN)2L2 (1), Co(SCN)2L2 (2), [Cd(SCN)2L2·2L]n (3) and [CdHg(SCN)4L2]n (4) have been prepared by self-assembly of a rigid functional pyridine ligand, trans-4-[4′-(N-methyl-N-hydroxyethyl)amimo]styryl pyridine (abbreviated as L) with M(SCN)x (M: Zn, Co, Cd, CdHg; x: 2, 4). The crystal structures indicate that 1 and 2 are mononuclear compounds while 3 and 4 are coordination
一系列新的配位化合物Zn(SCN)2 L 2(1),Co(SCN)2 L 2(2),[Cd(SCN)2 L 2 ·2L] n(3)和[CdHg(SCN)4 L 2 ] n(4)是通过将刚性的功能吡啶配体,反式-4- [4'-(N-甲基-N-羟乙基)氨基]苯乙烯基吡啶(缩写为L)与M( SCN)x(M:Zn,Co,Cd,CdHg;x:2、4)。晶体结构表明1和2是单核化合物,而3和4是配位聚合物。O–H⋯N,C–H⋯O,O–H⋯π和C–H⋯π氢键在最终晶体结构中起重要作用。已经测量了固态发光性能。结果表明,通过构架和引入不同的金属离子可以改变所有化合物的光致发光光谱。
