A unique supramolecular framework, [Zn 4 (H 2 O) 2 (2,5‐tdc) 4 (3,3'‐bpe) 3 ] n ( 1 ), was prepared by the self‐assembly of Zn(NO 3 ) 2 · 6H 2 O, 2,5‐thiophenedicarboxylic acid (2,5‐H 2 tdc), and 1,2‐bis(3‐pyridyl)‐ethene (3,3'‐bpe) under hydrothermal conditions. The coordination network of 1 can be simplified as a (3,4)‐connected dmc framework with a point symbol (4 · 8 2 )(4 · 8 5 ). The void space of a single network of 1 is filled by mutual interpenetration of four crystallographically equivalent nets, generating a fivefold interpenetrating architecture. Interestingly, the strong hydrogen bonds between the adjoining coordination networks further connect the interpenetrating architecture into a three‐dimensional supramolecular framework. Take the hydrogen bonds into consideration, the supramolecular structure of the title compound can be further regarded as an unprecedented 5‐nodal framework. The thermal stability, photoluminescent and photocatalytic properties of the title compound have also been investigated.
