Based on 1, 2,4, 5‐benzenetetracarboxylate acid (H 4 L), and mixed with bis(pyridyl)‐1, 2,4‐triazolate ligands, two novel 3D zinc(II) coordination polymers [Zn 3 (L)(3, 4′‐bpt) 2 ] ( 1 ) [3, 4′‐Hbpt = 1H‐3‐(3‐pyridyl)‐5‐(4‐pyridyl)‐1, 2,4‐triazole] and [Zn 4 (OH) 2 (L)(4, 4′‐bpt) 2 ] · 2H 2 O ( 2 ) [4, 4′‐Hbpt = 1H‐3, 5‐bis(4‐pyridyl)‐1, 2,4‐triazole] were synthesized and characterized by X‐ray crystallography, elemental analysis, and IR spectroscopy. The topological analysis results reveal that 1 can be simplified to a trinodal (3, 4,10) topology with the short Schläi symbol of (4 3 )(4 4 · 6 2 )(4 18 · 6 24 · 8 3 ) and a novel (3, 4,5)‐connected topology with (6 3 )(4 2 · 8 4 )(4 · 6 3 · 8 6 ) symbol for 2 , respectively. Thermogravimetric properties of 1 and 2 were also measured. In addition, the luminescent properties of 1 and 2 were investigated in the solid state at room temperature.
