  摘要：

  The synthesis and crystal structure of cis-Fe(BPE5)(2)Cl-2 (BPE5 = 1,2-diphospholanoethane). the first symmetrical cis-Fr(PP)(2)Cl-2 (PP = bidentate phosphine), is reported (monoclinic. P2(1)/n, a = 12.084(3) Angstrom, b = 14.059(2) Angstrom, c = 17.665(2) Angstrom, beta = 101.77(1)degrees, Z = 4). The overall structure and Fe-P and Fe-CI bend lengths of cis-Fe(BPE5)(2)Cl-2 more closely resemble those in Fe(PP3)Cl-2 complexes (PP3 = tripodal, tetradentate phosphine ligand) than in other Fe(PP)(2)Cl-2 complexes. In solution, cis-Fe(BPE5)(2)Cl-2 exhibits temperature-dependent paramagnetic behavior due to reversible dissociation of chloride. The dissociation of chloride was exploited in the synthesis of Fe(BPE5)(2)X-2 (X = Br, I) and [Fe(BPE5)(2)(L)(CI)](+). (L = CO, PMe3). The crystal structure of [cis-Fe(BPE5)(2)-(CO)(Cl)][BPh4] is reported (monoclinic, P2(1)/a, a = 12.938(3) Angstrom, b = 29.647(4) Angstrom, c = 13.131(3) Angstrom, beta = 107.89(2)degrees, Z = 4). The relative chelation strength of BPES in Fe(PP)(2)Cl-2 complexes is BPE5 approximate to DMPE > DEPE > DPrPE [DMPE = 1,2-bis(dimethylphoshino)ethane: DEPE = 1,2-bis(diethylphoshino)ethane; DPrPE = bis(di-n-propylphosphino)ethane].
