;Adding coordinates and cell parameter e.s.u. from the original
publication.

Adding symmetry operators, Hall symbol and the ITC spacegroup number
by intepreting the originaly reported space group 'C2/c' as having the
standard setting.

Adding Rwp, Rexp (background excluded), RI and mu values from the paper.
