The zinc ion in the title complex, [N,N′-bis(2-pyridylethyl)-2-(2-pyridyl)ethylamine-κ 4N]zinc(II) diperchlorate, [Zn(C21H24N4)](C1O4)2, displays a distorted tetrahedral configuration. The Zn-Npy distances range from 1.979(5) to 1.999(5) Å, while the Zn-Namine distance is 2.028(5) Å. The Npy-Zn-Npy and Npy-Zn-Namine 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 five-coordinate geometry normally observed in tripodal ligands of similar structure, and can be ascribed to the presence of weakly-coordinating anions and the ligand-metal chelate-ring size.
