The high-spin/low-spin bistability of spin-crossover (SCO) transition metal complexes is a fascinating property that attracts considerable interest because of its potential applications in molecular switches. The largest class of SCO compounds comprises monometallic, octahedral iron(II) complexes with six N-donor ligands, whose bistability involves interconversions of the high-spin (t2g) 4 (eg)...

Among the various homogenous electrocatalysts, especially Re(bpy)(CO)3Cl and [Ni(cyclam)]2+ were shown to be highly efficient for selective conversion of CO2 CO at moderate potentials. However, a purposeful combination ReI tricarbonyl unit with cyclam ligand hitherto received no attention. Herein, we report on series based Re complexes comprising original {N4} as well heteroatom-altered framewo...

Atropisomerism resulting from hindered rotation about single bonds can lead to molecules with centers of axial chirality and are widely used in asymmetric catalytic synthesis.1 Molecules containing planar centers of chirality have also been used as chiral ligands, particularly those containing η6-benzene and η5-cyclopentadienyl complexes.2 To our knowledge, there are no known synthetic methods ...
