                The magnetic spacegroup.
                If a string, it will be interpreted as one of the notations
                supported by MagneticSymmetryGroup, e.g., "R-3'c" or "Fm'-3'm".
                If a list of two ints, it will be interpreted as the number of
                the spacegroup in its Belov, Neronova and Smirnova (BNS) setting.
            lattice (Lattice/3x3 array): The lattice, either as a
                :class:`pymatgen.core.lattice.Lattice` or
                simply as any 2D array. Each row should correspond to a lattice
                vector. E.g., [[10,0,0], [20,10,0], [0,0,30]] specifies a
                lattice with lattice vectors [10,0,0], [20,10,0] and [0,0,30].
                Note that no attempt is made to check that the lattice is
                compatible with the spacegroup specified. This may be
                introduced in a future version.
            species ([Specie]): Sequence of species on each site. Can take in
                flexible input, including:
                i.  A sequence of element / specie specified either as string
                symbols, e.g. ["Li", "Fe2+", "P", ...] or atomic numbers,
                e.g., (3, 56, ...) or actual Element or Specie objects.

                ii. List of dict of elements/species and occupancies, e.g.,
                    [{"Fe" : 0.5, "Mn":0.5}, ...]. This allows the setup of
                    disordered structures.
            coords (Nx3 array): list of fractional/cartesian coordinates of
                each species.
            site_properties (dict): Properties associated with the sites as a
                dict of sequences, e.g., {"magmom":[5,5,5,5]}. The sequences
                have to be the same length as the atomic species and
                fractional_coords. Unlike Structure.from_spacegroup(),
                this argument is mandatory, since magnetic moment information
                has to be included. Note that the *direction* of the supplied
                magnetic moment relative to the crystal is important, even if
                the resulting structure is used for collinear calculations.
            coords_are_cartesian (bool): Set to True if you are providing
                coordinates in cartesian coordinates. Defaults to False.
            tol (float): A fractional tolerance to deal with numerical
                precision issues in determining if orbits are the same.
