【 摘 要 】

During the synthesis of an FeBr2 complex with the PNP ligand (R,R,SFc,SFc)-[Fe2(C5H5)2(C38H35NP2)] (1), single crystals of the di­chloro­methane 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 cyclo­penta­dienyl rings. The mean C—N bond length is 1.523 (4) Å. The inter­planar angle between the two connected cyclo­penta­dienyl 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 mol­ecules 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.
