In the title compound, [Co(H(2)O)(6)]Ni(C(12)H(11)N(2)O(5))·6H(2)O, the Ni(II) atom has a nearly square-planar coordination with two N and two O atoms of the N-(4-meth-oxy-2-oxidobenzyl-idene)glycylglycinate Schiff base ligand (L(3-)). The Co(II) atom sits on an inversion center and is coordinated to six aqua ligands in a slightly distorted octa-hedral geometry. The Co(H(2)O)(6) cations and NiL anions form columns along the a axis by O-H⋯O hydrogen bonds. Additional hydrogen bonds between the uncoordinated and coordinated water molecules help to consolidate the crystal packing.
在标题化合物[Co(H₂O)₆][Ni(C₁₂H₁₁N₂O₅)]₂·6H₂O中，Ni(II)原子与N-(4-甲氧基-2-氧化苄叉)甘氨酰甘氨酸席夫碱配体（L³⁻）的两个N原子和两个O原子形成近似平面正方形配位。Co(II)原子位于对称中心，以稍有畸变的八面体几何构型与六个水配体配位。[Co(H₂O)₆]²⁺阳离子和[NiL]⁻阴离子通过O—H⋯O氢键沿a轴形成柱体。未配位水分子和配位水分子之间的额外氢键有助于巩固晶体堆积。
