Five new coordination compounds with a tripodal ligand have been synthesized. 1 shows a dinuclear structure, 2, 4 and 5 display 1D zig-zag chain structures, and 3 exhibits an uncommon 1D chain structure. The results showed that the metal ions and anions have a distinct impact on the frameworks of the coordination compounds. Their photoluminescent properties were also investigated. [Display omitted] Five new coordination compounds, [Ag2(L3)2]·(ClO4)2 (1), [Zn(L3)(Cl)]·(ClO4)·H2O (2) [Zn2(L3)(Cl)4] (3), [Cu(L3)(Cl)]·(Cl)·2H2O (4) and [Cd(L3)(Cl)(H2O)]·(ClO4)·H2O (5), with the tripodal ligand N1-(2-amino-ethyl)-N1-pyridin-3-ylmethyl-ethane- 1,2-diamine (L3) have been synthesized. Interestingly, coordination compound 1 shows a dinuclear structure, coordination compounds 2, 4 and 5 display 1D zig-zag chain structures, and coordination compound 3 exhibits an uncommon 1D chain structure. The results showed that the metal ions and anions have a distinct impact on the frameworks of the coordination compounds. The photoluminescent properties of the ligand and coordination compounds were also investigated.
