Abstract:

During the synthesis of an FeBr2 complex with the PNP ligand (R,R,SFc,SFc)-[Fe2(C5H5)2(C38H35NP2)] (1), single crystals of the di-chloro-methane monosolvate of the Br- salt of the protonated ligand 1H+ were obtained serendipitously, i.e. [Fe2(C5H5)2(C38H36NP2)]Br·CH2Cl2. The crystal structure of 1H·Br·CH2Cl2 was determined by single-crystal X-ray diffraction. The mean bond lengths in the ferrocene units are Fe-C = 2.049 (3) Å and C-C = 1.422 (4) Å within the cyclo-penta-dienyl rings. The mean C-N bond length is 1.523 (4) Å. The inter-planar angle between the two connected cyclo-penta-dienyl rings is 49.2 (2)°. One ferrocene moiety adopts a staggered conformation, whereas the other is between staggered and eclipsed. The Br- ions and the CH2Cl2 mol-ecules are located in channels extending along <100>. One ammonium H atom forms a hydrogen bond with the Br- ion [H⋯Br = 2.32 (4) Å and C-H⋯Br = 172 (3)°]. The second ammonium H atom is not involved in hydrogen bonding.
