Abstract

Cis and trans-Cr–N2 complexes supported by the diphosphine ligand PPh2NBn2 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.
