Permutational character of dsd mechanisms in heptacoordinate chemistry

The permutational character of degenerate single and double dsd and of degenerate 4, 5-pyramidal processes is obtained for the heptacoordinate deltahedra. The symmetry properties of the paths of steepest descent and transition states of these rearrangements are derived. From this Permutational character, it would be possible to investigate the compatibility of these processes with the results of NMR line shape analysis of the dynamics of heptacoordinate complexes. This possibility is briefly discussed. © 1991 J.C. Baltzer AG, Scientific Publishing Company.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
