In the centrosymmetric title compound, [Ni(C(8)H(8)NO(3)S)(2)(H(2)O)(4)], the Ni(II) ion, which lies on an inversion centre, is six coordinated by four water mol-ecules and two propionate O atoms from two 2-pyridylsulfanylpropionate N-oxide ligands, forming a slightly distorted octa-hedral geometry. An intra-molecular O-H⋯O hydrogen bond stabilizes the mol-ecular conformation. The crystal packing is consolidated by inter-molecular O-H⋯O and C-H⋯O hydrogen bonding.
在中心对称的标题化合物[Ni(C₈H₈NO₃S)₂(H₂O)₄]中，位于对称中心的Ni(II)离子由四个水分子和来自两个2-吡啶硫基丙酸N-氧化物配体的两个丙酸根O原子进行六配位，形成略微扭曲的八面体几何构型。分子内的O—H⋯O氢键稳定了分子构象。晶体堆积通过分子间的O—H⋯O和C—H⋯O氢键得以巩固。
