标题配合物[N，N ' -双（2-吡啶基乙基）-2-（2-吡啶基）乙胺-κ 4n]锌（II）二高氯酸锌[Zn(C21H24N4)](ClO4)2中的锌离子呈畸变四面体构型。Zn-Npy的距离为1.979 (5)~ 1.999 (5)Å， Zn-Nam的距离为2.028 (5)Å。Npy-Zn-Npy和Npy-Zn-Nam的角范围分别为111.9(2)~ 119.6(2)°和102.3(2)~ 103.4(2)°。这种行为与具有类似结构的三足配体通常观察到的5坐标几何相反，可以归因于弱配位阴离子的存在和配体-金属螯合环的大小。
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.
