A series of Ag(i)–Cd(ii) hetero- and Ag(i) homo-nuclear coordination polymers based on 5-iodo-isophthalic acid and N-donor ancillary ligands†
Abstract
A series of novel heteronuclear/homonuclear coordination polymers {[Ag2(bpy)2(H2O)][Cd(5-iipa)2]·2H2O}n (1), {[Ag2(phen)2][Cd(5-iipa)2]·H2O}n (2), [Ag2(5-iipa)(bbi)0.5]n (3), {[Ag(5-iipa)][Ag(bpa)]}n (4), [Ag4(5-iipa)2(p-bix)2]n (5), have been solvothermally synthesized by 5-iodo-isophthalic acid (5-iipa) and N-donor ancillary ligands, such as bpy (4,4′-bipyridine), phen (1,10-phenanthroline), bbi (1,1′-(1,4-butanediyl)bis(imidazole)), bpa (1,2-bis(4-pyridyl)ethane) and p-bix (1,4-bis(imidazol-1-ylmethyl)-benzene). Compound 1 presents a unique “host–guest” structure. The structure of compound 2 is composed of Ag(I)–Cd(II) heteronuclear metal–organic layers, such layers are extended by weak Ag⋯I interactions into a 3D supramolecular framework. While 3, 4 and 5 are homonuclear Ag(I) coordination polymers.
