摘要：

The zinc ion in the title complex, [N,N'-bis(2-pyridylethyl)-2-(2-pyridyl)ethylamine-kappa(4)N] zinc(II) diperchlorate, [Zn(C21H24N4)](ClO4)(2), displays a distorted tetrahedral configuration. The Zn-N-py distances range from 1.979(5) to 1.999(5)Angstrom, while the Zn-N-amine distance is 2.028 (5) Angstrom. The N-py-Zn-N-py and N-py-Zn-N-amine angles range from 111.9(2) to 119.6(2)degrees and from 102.3(2) to 103.4(2)degrees, 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.
