The crystal structure of the title compound, (C6H14N)3[Sn(C2O4)2Cl2]Cl·H2O, contains three cyclo­hexyl­ammonium cations, one stannate(IV) dianion, one isolated chloride anion and one lattice water mol­ecule. The cyclo­hexyl­ammonium cations adopt chair conformations. In the complex anion, two bidentate oxalate ligands and two chloride anions in cis positions coordinate octa­hedrally to the central SnIV atom. The cohesion of the mol­ecular entities is ensured by the formation of N—H⋯O, O—H⋯O, O—H⋯Cl and N—H⋯Cl inter­actions involving cations, anions and the lattice water mol­ecule, giving rise to a layer-like arrangement parallel to (010).
