An aromatic tricarboxylic acid building block, [1,1′:3′,1″-terphenyl]-4,4″,5′-tricarboxylic (H3tptca), was used as a versatile linker for assembling, under hydrothermal conditions, series of 12 new coordination polymers (CPs) in the presence supporting N-donor ligands acting mediators crystallization. The obtained products were formulated [Mn(μ-Htptca)(phen)2]n·nH2O (1), [Zn(μ-Htptca)(2,2′-bipy)(H2O)]n·nH2O (2), [Ni(μ3-Htptca)(μ-4,4′-bipy)]n·2nH2O (3), [Co(μ3-Htptca)(μ-bpe)]n (4), [M3(μ3-tptca)2(phen)3(H2O)2]n·2nH2O (M = Co (5), Zn (6)), [Co2(μ4-tptca)(μ-OH)(2,2′-bipy)2]n (7), [Zn3(μ3-tptca)2(2,2′-bipy)3(H2O)2]n·4nH2O (8), {[Cd(H2biim)3][Cd2(μ3-tptca)(μ5-tptca)]}n (9), [Co2(μ4-tptca)(μ-bpa)(μ3-OH)(H2O)2]n·nH2O (10), [Ni3(μ3-tptca)2(μ-bpa)3(H2O)4]n·5nH2O (11), and [Co2(μ4-tptca)(μ-bpb)(μ-OH)]n (12), wherein phen, 2,2′-bipy, 4,4′-bipy, bpe, H2biim, bpa, bpb are 1,10-phenanthroline, 2,2′- 4,4′-bipyridine, 1,2-di(4-pyridyl)ethane, 2,2′-biimidazole, bis(4-pyridyl)amine, 1,4-bis(pyrid-4-yl)benzene, respectively. Crystal structures CPs 1–12 reveal broad diversity metal–organic networks that range from 1D chains (1, 2, 5, 6, 8) to 2D layers (3, 4, 7, 9, 11) 3D nets (10 12), including examples interpenetrated, polycatenated, topologically unique architectures. Structural features catalytic properties studied discussed. In particular, Zn(II) CP 8 acts an efficient recyclable heterogeneous catalyst mild cyanosilylation benzaldehydes, leading formation corresponding cyanohydrin up 99% yields. compounds widen growing family functional driven by terphenyl-tricarboxylate linkers.
