  Synthesis, Reactivity, and Structural Transformation of Mono- and Binuclear Carboranylamidinate-Based 3d Metal Complexes and Metallacarborane Derivatives

  摘要：

  A series of carboranylamidinate-based 3d metal complexes are reported. Treatments of 3d metal dichlorides (CoCl2, NiCl2(DME), CuCl2) with the lithium salts of carboranylamidines (Cab(N)H) generate the mononuclear C,N-coordinated complexes [(RN=C(closo-1,2-C2B10H10)-(NHR)](2)M (1-6; M = Co, Ni, Cu; R = iPr, Cy) in moderate yields, respectively. These complexes have similar structures in the solid state, in which the metal atom is coordinated to two nitrogen atoms and bonded to two cage carbon atoms in a distorted-tetrahedral geometry. As a noninnocent ligand, Cab(N)H can be modified to produce carboranylamidinate thiol (Cab(N)SH) and nido derivatives Dcab(N)H (9, 10), respectively. Reaction of cupric acetate with 1 equiv of CabNSH gave the binuclear complexes {[RN=C(closo-1,2-C2B10H10)(NHR)]SCu}(2) (R = iPr (7), Cy (8)) in 66 and 63% yields, respectively. The structure of 7 shows the formation of a Cu-Cu bond, and the geometry of the Cu2S2 core is planar. The zwitterionic nickel dicarbollide complexes (Dcab(N))Ni(PPh3)Cl (11, 12) were prepared by reactions of the lithium salts of Dcab(N)H (9, 10) with NiCl2(PPh3)(2) in THF. All complexes were characterized by elemental analysis and IR and NMR spectroscopy. The structures of 1, 3-5, 7, and 9-11 were further confirmed by single-crystal X-ray diffraction.

  affording the mononuclear Ni complex [1-S-(2′-(S)PPh2)-o-carborane]2Ni (3). Ni complexes 2 and 3 were characterized by IR, 1H NMR, and 31P NMR spectroscopy and elemental analysis. In addition, an X-ray structure analysis was performed on complex 2, where the o-carborane [S,C] ligand 1 was found to coordinate in a bidentate mode. EXAFS spectroscopy was performed on complex 3 to confirm that the coordination
