Notizen: Studies on Metal-Metal Bonds, VI /Observations on the EAN Rule and Bond Orders for Mn-Mn Compounds

Abstract
The metal metal distances of a representative number of organometallic manganese complexes vary from 2.50 Å to 3.23 Å, although all these compounds are predicted by the EAN Rule to possess single metal to metal bonds. It is no longer acceptable to predict bond orders from bond lengths, and vice versa.
