Abstract : Systemic investigation of various counter anions' effect on coordination assembly of ten Ag I complexes with the new linear ligand PTMP. Abstract : Ten silver(i ) coordination polymers {[Ag2 (PTMP)2 (L1)2 ]·3H2 O}∞ (1 ), {[Ag2 (PTMP)2 (L2)]·7H2 O}∞ (2 ), {[Ag2 (PTMP)2 (L3)]·2CH3 OH}∞ (3 ), {[Ag2 (PTMP)2 (L4)]·5H2 O}∞ (4 ), {[Ag(PTMP)]·0.5(L5)·2H2 O}∞ (5 ), {[Ag(PTMP)(L6)0.5 ]·H2 O}∞ (6 ), {[Ag3 (PTMP)3 (L7)]·2.25H2 O}∞ (7 ), [Ag(PTMP)(NO3 )]∞ (8 ), {[Ag(PTMP)]·(BF4 )}∞ (9 ) and {[Ag(PTMP)]·(CF3 SO3 )·0.5H2 O}∞ (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 CF3 SO3 − on the construction of complexes1–10 have been systematically investigated and discussed.
