Rb₂Mn₂(SO₄)₃, a new member of the langbeinite family

The structure of a new langbeinite, dirubidium dimanganese tris­ulfate, Rb₂Mn₂(SO₄)₃, has been determined and is shown to have cubic symmetry akin to the other members of the langbeinite family. The sturucture contains SO₄ tetra­hedra corner-linked to MnO₆ octa­hedra, generating a three-dimensional network. The Rb atoms are found in the cavities of this network.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
