Position structure from a model at room temperature retrieved from ICSD
The MSG is triclnic and the material is reported to exhibit a triclinic distortion below T_N, which is not fully characterized. Here, the structure is described with the positional structure at room temperature, including cell parameters, reported by other authors.
