Molecular modeling of dimetal systems: Part 4. Dirhenium bonds

The relationship between bond order (N), harmonic force constant (kr) and characteristic bond length free of strain (r0) for dirhenium bonds has been studied by molecular-mechanics simulation of suitable structures well characterized by X-ray diffraction. It follows the same trend, N=akr=abr0−5, found before for dimolybdenum and dichromium bonds.
