Homoleptic silver-bis(pyridine) coordination polymers: [Ag(L1)2]·(PF6), [Ag(L1)2]·(SbF6), [Ag(L1)2]·(BF4), [Ag(L2)]·(PF6), and [Ag(L3)1.5]·(CF3SO3)·(H2O)2 {L1 = (4-py)–CHN–C10H6–NCH–(4-py); L2 = (2-py)–CHN–C10H6–NCH–(2-py); L3 = (3-py)–CHN–C14H12–NCH–(3-p

Five homoleptic silver-bis(pyridine) coordination polymers, [Ag(L1)2]·(PF6) (1), [Ag(L1)2]·(SbF6) (2), [Ag(L1)2]·(BF4) (3), [Ag(L2)]·(PF6) (4), and [Ag(L3)1.5]·(CF3SO3)·(H2O)2 (5·(H2O)2), were prepared from AgX (X = PF6, SbF6, BF4, CF3SO3) and rigid bis(pyridine)-type linking ligands {L1 = (4-py)–CHN–C10H6–NCH–(4-py); L2 = (2-py)–CHN–C10H6–NCH–(2-py); L3 = (3-py)–CHN–C14H12–NCH–(3-py)}. Polymers 1–3 are isostructural and have the same non-interpenetrated, 3-D diamondoid framework, whose cavities are almost completely filled with the counterions. Polymer 4 is a 1-D chain polymer. Polymer 5·(H2O)2 is a 2-D α-arsenic-type polymer with a repeat unit of a 114-membered ring.
