  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.

  solid state by infrared and Mossbauer spectroscopic techniques. The structures of the antimony trihalide complexes appear to be based on halogen bridged polymers in which the stereochemical activity of the lone pair of electrons varies with the halogen, the highest p-character of the lone pair being observed with the trifluoride adduct. Mossbauer results for the PhSbI 2 complexes suggest a ψ-octahedral

  摘要描述了1,10-菲咯啉与SbX 3（X = F，Cl，Br）和PhSbI 2的单加合物的合成。这些化合物和2,2'-联吡啶与PhSbI 2之间的1：1加合物已主要通过红外和莫斯鲍尔光谱技术表征为固态。三卤化锑复合物的结构似乎是基于卤素桥联的聚合物，其中孤电子对的立体化学活性随卤素而变化，孤对电子的最高p-特征是通过三氟化物加合物观察到的。MoSsbauer的PhSbI 2配合物结果表明ψ-八面体立体化学，其中孤对和Ph基处于反式位置。
