Three coordination networks with the 1, 2,4‐triazole linking units 3‐(4′‐imidazole phenyl)‐5‐(pyrid‐2′′‐yl)‐1, 2,4‐triazole (HIppyt) and 3‐(pyrazin‐2′‐yl)‐5‐(4′‐(pyrid‐4′′‐yl)‐phenyl)‐1, 2,4‐triazole (Hpypypt), respectively, were synthesized and structurally characterized. The structures of [Mn(Ippyt) 2 · 2H 2 O] ( 1 ) and [Zn(Ippyt) 2 · 2H 2 O] ( 2 ) were found to be similar despite the presence of different metal ions. When Ippyt was replaced by pypypt to react with Zn(OAc) 2 · 2H 2 O, the 2D coordination polymer, {[Zn(pypypt) 2 ] · 2DMF} n ( 3 ) formed. The adjacent zinc(II) atoms with similar octahedral coordination environment are interlinked by four separate pypypt ligands to construct a 2D network structure. The biological activities of 1 and 3 were studied. The results indicate that 1 and 3 exhibit certain antimicrobial activities. Furthermore, solid‐state properties of thermal stability and photoluminescence properties at room temperature for these crystalline materials were also investigated.
