The zinc ion in the title complex, [N,N′-bis(2-pyridylethyl)-2-(2-pyridyl)ethylamine-κ4N]zinc(II) diperchlorate, [Zn(C21H24N4)](ClO4)2, displays a distorted tetrahedral configuration. The Zn—Npy distances range from 1.979 (5) to 1.999 (5) Å while the Zn—Nam distance is 2.028 (5) Å. The Npy—Zn—Npy and Npy—Zn—Nam angles range from 111.9 (2) to 119.6 (2)° and from 102.3 (2) to 103.4 (2)°, respectively. This behavior contrasts with the 5-coordinate geometry normally observed in tripodal ligands with similar structures, and can be ascribed to the presence of weakly coordinating anions and the ligand-metal chelate-ring size.
