  Synthesis and crystal structures of complexes containing an Fe → Cd donor-acceptor bond formed by reaction of trans-(CO)3Fe(Ph2Ppym)2 (Ph2Ppym = 2-(diphenylphospino)pyrimidine) with CdX2 (X = Cl, Br, I, SCN, ClO4)

  摘要：

  Five complexes of cadmium(II) containing an Fe-->Cd donor-acceptor bond have been synthesized from the reaction of a neutral organometallic tridentate ligand trans-(CO)(3)Fe(Ph(2)Ppym)(2) (Ph(2)Ppym=2-(diphenylphosphino)pyrimidine) with various cadmium(II) salts and fully characterized by single-crystal X-ray analysis: [(CO)(3)Fe(mu-Ph(2)Ppym)(2)CdCl2](2) . 0.5CHCl(3) . 2.5thf (1) belongs to space group P (1) over bar with a=12.311(4), b=17.083(2), c=21.994(12) Angstrom, alpha=103.34(2), beta=92.42(5), gamma=101.07(1)degrees and Z=2; [(CO)(3)Fe(mu-Ph(2)Ppym)(2)CdBr2]. 2CH(2)Cl(2) (2) to space group C2/c with a=25.691(1), b=19.953(1), c=8.584(1) Angstrom, beta=102.14(1)degrees and Z=4; [(CO)(3)Fe(mu-Ph(2)Ppym)(2)CdI2], 3, space group P2(1)/n with a=13.811(1), b=14.019(1), c=19.738(1) Angstrom, beta=102.26(1)degrees and Z=4; [(CO)(3)Fe(mu-Ph(2)Ppym)(2)Cd(NCS)(2)]. 2CH(2)Cl(2) (4) to space group P (1) over bar with a=9.986(1), b=12.014(1), c=20.501(1) Angstrom, alpha=98.10(1), beta=91.78(1), gamma=112.07(1)degrees and Z=2; [(CO)(3)Fe(mu-Ph(2)Ppym)(2)Cd(CH3CN)(H2O)]. 2ClO(4) . 15CHCl(3) (5) to space group P (1) over bar with a=12.063(2), b=12.922(2), c=17.502(3) Angstrom, alpha=75.61(1), beta=71.14(1), gamma=79.12(1)degrees and Z=2. In this series of complexes, the Fe-Cd distance lies between 2.651(2) and 2.818(1) Angstrom which is indicative of the existence of donor-acceptor metal-metal bonding. Although the different halides have no significant influence on the Fe-Cd bond distance, the SCN- group does shorten the Fe-Cd distance owing to its delocalized electronic structure in 4. Furthermore, in the [(CO)(3)Fe(mu-Ph(2)Ppym)(2)Cd(MeCN)(H2O)](2+) cation of complex 5, the dative Fe-->Cd bond distance, being comparable with the covalent Fe-Cd bond distance in related heterobimetallic compounds, is mainly determined by the electronic characteristics of this bond rather than the restriction imposed by the rigid bridging ligand.
