A series of silver(i) coordination polymers of a new linear 4-((pyridin-4-ylthio)methyl)pyridine ligand: the role of organic and inorganic anions

Abstract

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.
