Abstract
Three coordination polymers, [Co(L)(tbta)]n (1), [Ag(L)(H2O)·(Hhpht)]n (2) and [Ag2(L)1.5(oba)]n (3) (L = 1,4-bis(2-methylbenzimidazol-1-ylmethyl)benzene, H2tbta = tetrabromoterephthalic acid, H2hpht = homophthalic acid, H2oba = 4,4′-oxybis(benzoic acid)), have been hydrothermally synthesized and structurally characterized. Complex 1 displays a 2-D uninodal 4-connected sql network, 2 and 3 feature chain structures, which further generate 2D supramolecular networks through hydrogen bonding interactions. The thermal and fluorescence properties of 1–3 have been carried out and discussed.
