Abstract

The asymmetric unit of the title compound, 2C10H18N+·HPO42−·1.5C4H4O4, contains two adamantan-1-aminium cations, one hydrogen phosphate anion, and one and a half mol­ecules of fumaric acid, one of which exhibits crystallographic inversion symmetry. Each HPO42− anion is hydrogen bonded, via all of its O atoms, to four NH3+ groups of the adamantan-1-aminium cations, forming chains along [100]. These chains are, in turn, inter­connected via a set of O—H⋯O hydrogen bonds involving the fumaric acid solvent mol­ecules, forming layers parallel to (001). Weak C—H⋯O inter­actions lead to a consolidation of the three-dimensional set-up.
