On the incorrect assignment of space groups V. Revisions of non-centrosymmetric to centrosymmetric structure without changing crystal system

Twelve examples of crystal structures, which were originally described as non-centrosymmetric, are properly~ described as centrosymmetric. Of which two triclinic and eight monoclinic cases are simply revised by insertion~ of a missing centre of symmetry, and also one example each changes from orthorhombic Pbn2 1 to Pnma and Pma2 to Pmna.
