  Open and half-open manganocene chemistry: more associated salts

  摘要：

  The reaction of MnCI2 With 1 equiv each of NaC5H5 and K(2,4-C7H11) (C7H11 = dimethylpentadienyl) leads to Mn2(C5H5)2(2,4-C7H11). This species may be considered to be an associated salt of high-spin Mn(C5H5)+ and the 18-electron Mn(C5H5)(2,4-C7H11)-. In accord with this, magnetic susceptibility measurements demonstrate the presence of five unpaired electrons. A single-crystal X-ray diffraction study has been undertaken. The space group is P2(1)/m with a = 7.495 (2), b = 12.500 (7), c = 8.678 (3) angstrom, beta = 106.88 (2)-degrees, and V = 778.0 angstrom3, for Z = 2. The structure has been refined to discrepancy indexes of R = 0.075 and R(w) = 0.078. The reaction of MnCl2 with 2 equiv of K[3-CH3-1,5-(Me3Si)2C5H4] also leads to an associated salt, K{Mn[3-CH3-1,5-(Me3Si)2C5H4]3}, again with high-spin Mn2+ (five unpaired electrons). An X-ray diffraction study revealed that the Mn2+ center experiences trigonal planar coordination with the three eta1-bound dienyl ligands, while K+ is encapsulated within the three dienyl chains. The space group at -140-degrees is Pcab (No. 61), with a = 19.180 (4), b = 26.895 (4), c = 18.843 (5) angstrom, and V = 9720.1 angstrom3 for Z = 8. The structure has been refined to discrepancy indexes of R = 0.068 and R(w) = 0.068.
