Abstract
In the title compound, (C(6)H(10)N(2))[Ni(C(7)H(3)NO(4))(2)]·5H(2)O, the Ni(II) ion is six-coordinated by two N and four O atoms from two pyridine-2,6-dicarboxyl-ate ligands in a distorted octa-hedral fashion. The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O and weak C-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distances = 3.4669 (19) and 3.764 (2) Å].
摘要
在标题化合物（C₆H₁₀N₂）[Ni（C₇H₃NO₄）₂]·5H₂O中，Ni（II）离子由来自两个吡啶-2,6-二羧酸酯配体的两个N原子和四个O原子以扭曲的八面体构型进行六配位。晶体堆积通过分子间的O—H⋯O、N—H⋯O以及弱的C—H⋯O氢键和π-π相互作用[质心-质心距离 = 3.4669（19）和3.764（2）Å]得以稳定。
