Four new metal‐organic coordination compounds [Ni(L4) 2 ](ClO 4 ) 2 · 2H 2 O ( 1 ), [Cu 2 (L4) 2 (H 2 O) 2 (Cl)](Cl) 3 · 5H 2 O ( 2 ), [Cu 2 (L3) 2 (H 2 O)(Cl)](Cl) 2 · (NO 3 ) · 6H 2 O ( 3 ), and [Cu(L3)(H 2 O)(NO 3 )](NO 3 ) · H 2 O ( 4 ), were synthesized and characterized by X‐ray crystallography with two isomeric tripodal ligands N 1 ‐(2‐amino‐ethyl)‐N 1 ‐pyridin‐3‐ylmethyl‐ethane‐1,2‐diamine (L3) and N 1 ‐(2‐amino‐ethyl)‐N 1 ‐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.
