SrO is Molybdenum Carbide MAX Phase-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing SrO6 pentagonal pyramids. All Sr–O bond lengths are 2.60 Å. O2- is bonded to six equivalent Sr2+ atoms to form a mixture of edge, corner, and face-sharing OSr6 octahedra. The corner-sharing octahedral tilt angles are 47°.
