| Abstract: | Four new metal-organic coordination compounds [Ni(L4)2](ClO4)2 · 2H2O ( 1 ), [Cu2(L4)2(H2O)2(Cl)](Cl)3 · 5H2O ( 2 ), [Cu2(L3)2(H2O)(Cl)](Cl)2 · (NO3) · 6H2O ( 3 ), and [Cu(L3)(H2O)(NO3)](NO3) · H2O ( 4 ), were synthesized and characterized by X-ray crystallography with two isomeric tripodal ligands N1-(2-amino-ethyl)-N1-pyridin-3-ylmethyl-ethane-1,2-diamine (L3) and N1-(2-amino-ethyl)-N1-pyridin-4-ylmethyl-ethane-1,2-diamine (L4), respectively. It was found that coordination compound 1 exhibits mononuclear structure, and coordination compound 2 displays a one dimensional (1D) zigzag chain structure. Coordination compound 3 shows interesting cyclic hexanuclear structure, whereas coordination compound 4 is a 1D zigzag chain structure. The results indicate that metal ions, organic ligands, and anions have remarkable influence on the formation and structures of the coordination compounds. |
