  Synthesis, characterizations and crystal structures of antimony(III) complexes with nitrogen-containing ligands

  摘要：

  Six antimony adducts with N-donor neutral ligands (1,10-phenanthroline, 4,4'-bipyridine) have been obtained following the reaction of antimony halides with phenanthroline and 4,4'-bipyridine. By changing the solvent and stoichiometry, we obtained six different complexes, Sb(phen)Cl(3) (1), Sb(phen)Br(3) (2), Sb(2)(phen)(4)Br(8)(3) and Sb(bpy)Cl(3)(4), Sb(bpy)(2)Cl(3) (5), Sb(bpyH center dot bpyH(2))Br(6) (6) (where phen = 1,10-phenanthroline, bpy = 4,4'-bipyridine). All the complexes have been characterized via elemental analysis, FT-IR and NMR ((1)H, (13)C) spectroscopy. The crystal structures of complexes 2, 3 and 6 have been determined by X-ray single crystal diffraction.The structural analysis show that the coordination sphere around antimony atom in complex 2 is a distorted square pyramid, coordinated by three bromine atoms and two nitrogen atoms from phen. In complex 3, the central antimony atom is six-coordinated through four bromine atoms and two nitrogen atoms forming a distorted octahedral geometry. Besides that, there are also uncoordinated 1,10-phenanthroline bonded by hydrogen bonds and pi-pi stacking interactions, which is rarely observed in previous reports. The crystal structure of complex 6 consists of bpyH center dot bpyH(2) trications and hexabromoantimonate trianions. The antimony atom in the anion has a distorted octahedral environment. Additionally, all complexes present a 3D framework built up by N-H center dot center dot center dot Br, C-H center dot center dot center dot Br and C-H center dot center dot center dot Cl weak hydrogen bonds interactions.
