The crystal structure of LaCaCuGaO 5 has been investigated by single crystal X‐ray analysis. It crystallizes with orthorhombic symmetry, space group C 2v 22 –Ima2, a = 15.8467, b = 5,5077, c = 5.3188 Å, Z = 4. LaCaCuGaO 5 belongs to the mineral Brownmillerite showing layers of corner connected CuO 6 octahedra linked by GaO 4 tetrahedra. The La 3+ and Ca 2+ ions are distributed statistically over one crystallographic point position.
