[Zn2(HL)(phen)2(H2O)2]n (3), and [Zn5(L)2(phen)4(H2O)3]n.2nH2O (4). Both 1 and 2 are three-dimensional (3D) zinc(II)-hydroxide cluster based coordination frameworks. 1 contains distorted chairlike hexanuclear Zn6(mu3-OH)2 cluster units as secondary building blocks. Each Zn6(mu3-OH)2 unit connects six others through the three-connected nodes of L5- ligands into a 3D rigid and condensed coordination network, whereas
在有或没有辅助2,2'-联吡啶(2,2'-bpy)和1,10-菲咯啉(phen)配体及其存在下合成部分或全部去质子化的苯五甲酸(H5L)的第一配位化合物表征晶体结构和光致发光性质。他们的公式是[Zn6(mu3-OH)2(L)2(H2O)6] n(1),[Zn5(mu3-OH)2(HL)2(2,2'-bpy)2] n(2 ),[Zn2(HL)(phen)2(H2O)2] n(3)和[Zn5(L)2(phen)4(H2O)3] n.2nH2O(4)。1和2都是基于三维(3D)氢氧化锌(II)簇的协调框架。1包含扭曲的椅子状六核Zn6(mu3-OH)2簇单元,作为次要构建基块。每个Zn6(mu3-OH)2单元通过L5-配体的三个连接节点将六个其他单元连接成一个3D刚性和稠密配位网络,而在2个中,每个五核Zn5(mu3-OH)2单元通过三个连接的[HL] 4-节点将其他六个Zn5(mu3-OH)2
