Abstract: Two enantiomeric non-heme iron complexes [Fe( R , R -BPMCN)(CH 3 CN) 2 ](SbF 6 ) 2 and [Fe( S , S -BPMCN)(CH 3 CN) 2 ](SbF 6 ) 2 (BPMCM = N , N ′-dimethyl- N , N ′-bis(pyridin-2-ylmethyl)-cyclohexane-1,2-diamine, C 22 H 28 N 4 ) were obtained in parallel syntheses starting from the enantiomerically pure R , R and S , S BPMCN ligands. The Fe II cations have a distorted octahedral FeN 6 geometry formed by a chelating N , N , N , N -tetradentate BPMCN ligand and two molecules of acetonitrile. The ligand adopts a cis - α topology with the two pyridine groups coordinated trans to each other. In the crystals, a system of C—H...F hydrogen bonds links the cations to the hexafluoroantimonate anions, resulting in a three-dimensional architecture.
