In the title molecular salt, (C4H10NO)2[CoCl4], the morpholinium cations adopt chair conformations and the tetrachloridocobaltate(II) anion is significantly distorted from regular tetrahedral 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.
