Ten silver(I) coordination polymers [Ag2(PTMP)2(L1)2]·3H2O}∞ (1), [Ag2(PTMP)2(L2)]·7H2O}∞ (2), [Ag2(PTMP)2(L3)]·2CH3OH}∞ (3), [Ag2(PTMP)2(L4)]·5H2O}∞ (4), [Ag(PTMP)]·0.5(L5)·2H2O}∞ (5), [Ag(PTMP)(L6)0.5]·H2O}∞ (6), [Ag3(PTMP)3(L7)]·2.25H2O}∞ (7), [Ag(PTMP)(NO3)]∞ (8), [Ag(PTMP)]·(BF4)}∞ (9) and [Ag(PTMP)]·(CF3SO3)·0.5H2O}∞ (10) derived from a new flexible 4-((pyridin-4-ylthio)methyl)pyridine ligand (abbreviated as PTMP) have been synthesized and fully characterized (L1 = pentafluoropropionate, L2 = malonate, L3 = 2,2,3,3,4,4-hexafluoropentanedioate, L4 = 1,4-cyclohexanedicarboxylate, L5 = 1,4-benzenedicarboxylate, L6 = 1,1′-biphenyl-4,4′-dicarboxylate and L7 = 2-hydroxypropane-1,2,3-tricarboxylate). These coordination polymers exhibit fascinating 1-D chains and 2-D and 3-D network structures with the PTMP functioning as a linear building block. Under a solvent medium with small van der Waals volume, the tuning effect of various anions from monocarboxylate to polycarboxylate (L1–L7) and the inorganic NO3−, BF4− and CF3SO3− on the construction of complexes 1–10 have been systematically investigated and discussed.
合成并全面表征了十种银(I)配位聚合物[Ag2(PTMP)2(L1)2]·3H2O}∞ (1),[Ag2(PTMP)2(L2)]·7H2O}∞ (2),[Ag2(PTMP)2(L3)]·2CH3OH}∞ (3),[Ag2(PTMP)2(L4)]·5H2O}∞ (4),[Ag(PTMP)]·0.5(L5)·2H2O}∞ (5),[Ag(PTMP)(L6)0.5]·H2O}∞ (6),[Ag3(PTMP)3(L7)]·2.25H2O}∞ (7),[Ag(PTMP)(NO3)]∞ (8),[Ag(PTMP)]·(BF4)}∞ (9) 和 [Ag(PTMP)]·(CF3SO3)·0.5H2O}∞ (10),这些聚合物是基于一种新型柔性4-((吡啶-4-基硫)甲基)吡啶配体(简称为PTMP)。其中L1 = 五氟丙酸根,L2 = 马来酸根,L3 = 2,2,3,3,4,4-六氟戊二酸根,L4 = 1,4-环己烷二羧酸根,L5 = 1,4-苯二甲酸根,L6 = 1,1′-联苯-4,4′-二羧酸根,L7 = 2-羟基丙烷-1,2,3-三羧酸根。这些配位聚合物展示了迷人的一维链和二维、三维网络结构,其中PTMP作为线性构建块。在具有小范德华体积的溶剂介质下,系统研究并讨论了单羧酸根到多羧酸根(L1–L7)以及无机根离子NO3−、BF4−和CF3SO3−对聚合物1-10构造的调节效应。
