摘要: Chemical bonding of neutral rhenium trichloride Re3Cl9 and doubly charged has been brought into question in the current work. Despite recently reported propositions π-aromaticity based on negative nuclear independent chemical shift (NICS) values[ 1 , 2 ] to contrary, it is shown be a purely classical molecule, according results developed Adaptive Natural Density Partitioning (AdNDP) analysis.[ 3-5 The formation three consecutive double bonds triatomic cycle formed by atoms that was initially predicted Cotton et al.[ 6-8 confirmed. picture changes dramatically upon addition two excess electrons Re3Cl9. resulting cluster are held together via single Re-Re σ-bonds, Re-Cl-Re totally delocalized π-bond valence d atomic orbitals (d-AO) with minor contributions coming from density associated wi...
