  Isopropyltetramethylcyclopentadienyl samarium chemistry: structural studies of divalent (C5Me4iPr)2Sm(THF) and mixed valent [(C5Me4iPr)2Sm]2(μ-Cl)

  摘要：

  The isopropyltetramethylcyclopentadienyl samarium complexes ((C5Me4Pr)-Pr-i)(2)Sm(THF), 1, and [((C5Me4Pr)-Pr-i)(2)Sm](2)(mu-Cl), 2, have been isolated and structurally characterized. Divalent 1 crystallizes from hot toluene as a monosolvate in space group P3(1)21 with a = b = 15.494(2) Angstrom, c = 9.7724(7) Angstrom, alpha = beta = 90 degrees, gamma = 120 degrees, V = 2031.6(5) Angstrom(3) and D-calcd = 1.346 g/cm(3) Z = 3 and T = 163 K. 1 has a 141.6 degrees ring centroid-Sm-ring centroid angle and an average Sm-C distance of 2.80(3) Angstrom. 2 crystallizes from hot toluene in space group P1 with a = 9.616(2) Angstrom, b = 15.479(2) Angstrom, c = 17.844(1) Angstrom, alpha = 111.671(4)degrees, beta = 93.488(8)degrees gamma = 107.494(9)degrees, V = 2309.3(5) Angstrom(3) and D-calcd = 1.423 g/cm(3), Z = 2 and T = 163 K. The two bent metallocene units in 2 are connected by an asymmetrical chloride bridge which has a 169.88(4)degrees Sm(1)-Cl-Sm(2) angle and 2.678(1) Angstrom Sm(1)-Cl and 2.891(1) Angstrom Sm(2)-Cl distances. The 2.69(2) Angstrom average Sm(1)-C((C5Me4Pr)-Pr-i) distance is characteristic of Sm(III) and the 2.80(2) Angstrom average Sm(2)-C((C5Me4Pr)-Pr-i) distance is characteristic of Sm(II).
