catena-Poly[1,2,2-trimethyl-cyclo-pentane-1,3-diammonium [aluminate(III)-μ-(hydrogen phosphato)-μ-phosphato]].
In the title compound, {(C(8)H(20)N(2))[Al(HPO(4))(PO(4))]}(n), the Al(III) atom is coordinated by four O atoms from two HPO(4) (2-) and two PO(4) (3-) groups in a distorted tetra-hedral geometry. Each AlO(4) unit shares four O atoms with four adjacent PO(4) units, leading to an anionic chain along [100]. The negative charge of the chain is compensated by doubly protonated camphoric amine cations. N-H⋯O hydrogen bonds connect the cations and the anionic chains. O-H⋯O hydrogen bonds are present in the chain.
