On the incorrect assignment of space groups III. Revised P1 structures

Revisions for 8 crystal structures are reported based on space groups of higher symmetry than the original reported P1. Three cases have been revised from P1 to P1 , and the remaining cases have been changed in both the crystal class and the Laue symmetry, four from 1 to 2/m and one to 4/m. Among the non centrosymmetric to centrosymmetric corrections, only one structure has been re refined based on the original intensity data.
