Abstract

Cis and trans-Cr-N₂ complexes supported by the diphosphine ligand P^Ph₂N^Bn₂ have been prepared. Positioned pendant amines in the second coordination sphere influence the thermodynamically preferred geometric isomer. Electronic structure calculations indicate negligible Cr-N₂ back-bonding; rather, electronic polarization of N₂ ligand is thought to stabilize Cr-N₂ binding.
