Abstract: The title compound contains layers built up from isolated BO3 triangles and MgO6 octahedra, interleaved with SrO9 polyhedra to form a three-dimensional framework. The Sr atom is nine-coordinate in a distorted tricapped trigonal prismatic geometry. Sr, B and one O atom have m point symmetry and Mg 2/m point symmetry.
