MgO6HPO3 crystallizes in the trigonal R3 space group. The structure consists of three phosphonic acid molecules inside a MgO6 framework. In the MgO6 framework, Mg(1) is bonded in an octahedral geometry to three equivalent O(2) and three equivalent O(3) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Mg(1) and one O(3) atom. In the second O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Mg(1) and one O(2) atom.
