| Abstract: | Four Ag(I) coordination polymers, formulated as [Ag(L1)(tpa)0.5] n (1), {[Ag(L2)(ndc)0.5]·0.5H2ndc} n (2), [Ag(L3)0.5(ndc)0.5] n (3) and {[Ag(L3)]·H3bptc} n (4) (L1 = 4,4′-bis(pyrazole-1-ylmethyl)-biphenyl, L2 = 4,4′-bis(3,5-dimethylpyrazol-1-ylmethyl)-biphenyl, L3 = 1,4-bis(3,5-dimethylpyrazol-1-ylmethyl)benzene, H2tpa = terephthalic acid, H2ndc = 2,6-naphthalenedicarboxylic acid, H4bptc = 3,3′,4,4′-biphenyltetracarboxylic acid), have been hydrothermally synthesized and structurally characterized. Complex 1 features the rare binodal (4,4)-connected 2D 4,4L10 topological network with a point symbol of {32·4.62·7}2{32·62·72}. Complex 2 has a folded ladder-like chain structure, which is further extended into a 3D supramolecular network via O–H···O hydrogen bonding and π···π stacking interactions. Complexes 3 and 4 both possess 1D zigzag chain structures. Complex 3 is further extended into a binodal (3,4)-connected network with the point symbol of {4.84·10}{62·82}2 by Ag···O weak interactions, while complex 4 is further connected through O–H···O hydrogen bonding and π···π interactions to afford a 2D supramolecular structure. The photoluminescence spectra and photocatalytic properties of these complexes for degradation of methylene blue and methyl orange are reported. |
