Mn2Ga(PO4)4 crystallizes in the cubic I-43m space group. Mn(1) is bonded to four equivalent O(1) atoms to form MnO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. All Mn(1)-O(1) bond lengths are 1.88 Å. Ga(1) is bonded to four equivalent O(3) atoms to form GaO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. All Ga(1)-O(3) bond lengths are 1.85 Å. P(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form PO4 tetrahedra that share  a cornercorner with one Ga(1)O4 tetrahedra and corners with two equivalent Mn(1)O4 tetrahedra. The P(1)-O(2) bond length is 1.49 Å. The P(1)-O(3) bond length is 1.54 Å. Both P(1)-O(1) bond lengths are 1.53 Å. There are three inequivalent O sites. In the first O site, O(2) is bonded in a single-bond geometry to one P(1) atom. In the second O site, O(3) is bonded in a bent 150 degrees geometry to one Ga(1) and one P(1) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one Mn(1) and one P(1) atom. Linkers: 24 [O]P([O])([O])=O. Metal clusters: 12 [Mn] ,6 [Ga]. The MOF has largest included sphere 10.76 A, density 1.15 g/cm3, surface area 2906.37 m2/g, accessible volume 0.60 cm3/g
