The title salt, (C(6)H(11)N(2))(2)[Cd(C(7)H(3)NO(4))(2)], displays a discrete mononuclear structure, in which the central Cd(II) atom is six-coordinated in a distorted octa-hedral coordination geometry by two N and four O atoms from two different pyridine-2,6-dicarboxyl-ate anions in an O(2),N,O(6)-tridentate chelation mode. The crystal packing is stabilized by N-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distance = 3.576 (5) Å].
标题盐(C₆H₁₁N₂)₂[Cd(C₇H₃NO₄)₂]呈现出离散的单核结构,其中中心Cd(II)原子通过来自两个不同吡啶 - 2,6 - 二羧酸根阴离子的两个N原子和四个O原子以O(2),N,O(6)-三齿螯合模式在扭曲的八面体配位几何中进行六配位。晶体堆积通过N - H⋯O氢键和π - π相互作用[质心 - 质心距离 = 3.576(5)Å]得以稳定。
