A series of transition metal coordination complexes, [Zn 3 (2‐aptt) 2 (1,4‐bdc) 2 ] n ( 1 ), [Zn 4 (2‐aptt) 4 (H 2 pma) 2 (H 2 O) 4 ] n ( 2 ), [Zn 2 (2‐aptt) 2 (3‐pc) 2 (H 2 O) 4 ] ( 3 ), and [Pb(2‐ptt)] n ( 4 ) were synthesized under solvothermal conditions using the pyridine containing mercapto‐triazole ligand 2‐apttH [4‐amino‐3‐(2‐pyridyl)‐1H‐1,2,4‐triazole‐5‐thione] as a main building block. Their structures were determined by single‐crystal X‐ray diffraction analyses and further characterized by elemental analyses and IR spectroscopy. Notably, desamination reaction exists in the formation of complex 4 , in which the ligand 2‐apttH deaminated to generate the ligand 2‐pttH 2 [3‐(2‐pyridyl)‐1H‐1,2,4‐triazole‐5‐thione]. The four complexes exhibit structural diversity: complex 1 presents an interesting 3D framework, complexes 2 and 4 feature 2D networks, whereas complex 3 shows dinuclear structure. Moreover, the luminescent properties of complexes 1 – 4 , the first and second ligands were also studied.
