In the title complex, [Ni(CHNO)(CHOS)(HO)], the Ni cation is situated on a twofold rotation axis and exhibits a distorted octa-hedral NO coordination environment defined by a tridentate pyridine-2,6-di-carb-oxy-lic acid dianion (dpa), two dimethyl sulfoxide (DMSO) mol-ecules, and a water mol-ecule. In the crystal, the complex mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bonds into a three-dimensional network whereby DMSO mol-ecules from neighboring complexes overlap to form layers parallel to (001), alternating with layers of Ni-dpa moieties. The title complex is isotypic with its cobalt(II) analogue.
在标题配合物[Ni(CHNO)(CHOS)(HO)]中，镍阳离子位于一个二次旋转轴上，呈现出由三齿吡啶-2,6-二羧酸二价阴离子（dpa）、两个二甲基亚砜（DMSO）分子和一个水分子定义的扭曲八面体NO配位环境。在晶体中，配合物分子通过O-H⋯O和C-H⋯O氢键连接成三维网络，相邻配合物中的DMSO分子相互重叠形成平行于(001)的层，与Ni-dpa部分的层交替排列。标题配合物与其钴(II)类似物同构。
