Abstract

In the title compound, [ZnI(2)(C(24)H(16)N(6))], the Zn(II) ion is five-coordinated in a distorted trigonal-bipyramidal geometry by an N,N,N-tridentate 2,3,5,6-tetra-2-pyridinylpyrazine ligand and two iodide ions. The I(-) ions both occupy equatorial sites. Within the ligand, the dihedral angles between the central pyrazine ring and the two chelating pyridine (py) rings are 14.74 (17) and 26.72 (18)°. The equivalent angles for the non-coordinating py rings are 28.63 (16) and 42.19 (17)°. There is no aromatic π-π stacking in the crystal.

摘要

在标题化合物[ZnI₂(C₂₄H₁₆N₆)]中，Zn(II)离子由一个N,N,N-三齿的2,3,5,6-四(2-吡啶基)吡嗪配体和两个碘离子以扭曲的三角双锥几何构型五配位。I⁻离子均占据赤道位置。在配体内，中心吡嗪环与两个螯合吡啶（py）环之间的二面角分别为14.74 (17)°和26.72 (18)°。非配位py环的等效角度分别为28.63 (16)°和42.19 (17)°。晶体中不存在芳香π-π堆积。
