The self-assembly of the two zinc(II) metal-organic frameworks, [Zn 2 (L) (bdc) 2 ]Á3MeOHÁ4H 2 O} n (1, L = 2-(pyridin-4-yl)-3H-imidazo[4,5-c]pyridine, H 2 bdc = 1,4-benzenedicarboxylic acid) and [Zn 2 (L)(bdc) 2 ]Á2DMFÁH 2 O} n (2), was achieved under mild reaction conditions. Both compounds 1 and 2 were structurally characterized by single-crystal X-ray diffraction analysis. Interestingly, the coordination modes of the ligand L in two structures are entirely different. Compounds 1 and 2 were made up of paddle wheel-shaped {Zn 2 (O 2 C) 4 } secondary building unit (SBU) clusters, which adopted three-dimensional structures with a pcu topology. Rich weak interactions were observed in the structures of both 1 and 2. The uncoordinated imidazole and pyridine moieties exhibited electron donor-acceptor interactions, π-π stacking, hydrogen bonding, and CH-π interactions. These interactions also facilitated the abilities of
