In the title mol-ecular salt, (C(4)H(10)NO)(2)[CoCl(4)], the morpholinium cations adopt chair conformations and the tetra-chloridocobaltate(II) anion is significantly distorted from regular tetra-hedral geometry [Cl-Co-Cl = 102.183 (19)-117.59 (2)°]. The Co-Cl bond lengths for the chloride ions not accepting hydrogen bonds are significantly shorter than those for the chloride ions accepting such bonds. In the crystal, the components are linked by N-H⋯O and N-H⋯Cl and bifurcated N-H⋯(O,Cl) hydrogen bonds to generate (100) sheets.
在标题分子盐(C₄H₁₀NO)₂[CoCl₄]中，吗啉鎓阳离子呈椅式构象，四氯合钴(II)阴离子明显偏离正四面体几何形状[Cl-Co-Cl = 102.183 (19)-117.59 (2)°]。不接受氢键的氯离子的Co-Cl键长明显短于接受氢键的氯离子的Co-Cl键长。在晶体中，各组分通过N-H⋯O和N-H⋯Cl以及分叉的N-H⋯(O,Cl)氢键相连，形成(100)层。
