The reaction of the stable carbene, >:>&z.ub1s;CN(Pri)C2Me2 &z.ub1e;NPri, with InX3, X 4;= 4;Cl or Br, yielded either the 1∶1 or 1∶2 complexes, [InX3{&z.ub1s;CN(Pri)C2Me2N&z.ub1e;Pri}] and [InX3{&z.ub1s;CN(Pri)C2Me2N&z.ub1e;Pri}2], depending upon the stoichiometry employed. X-Ray crystallography showed one of the 1∶1 adducts, X 4;= 4;Br, to be monomeric and tetrahedral. The 2∶1 adducts have a trigonal-bipyramidal geometry with two halides axial and one equatorial. Conductivity and NMR studies suggested all these complexes retain their neutrality in solution. Treatment of InX3 with 1 equivalent of &z.ub1s;CN(Pri)C2Me2N&z.ub1e;Pri and half an equivalent of water afforded the ionic compounds [H&z.ub1s;CN(Pri)C2Me2N&z.ub1e;Pri] [InX4{&z.ub1s;CN(Pri)C2Me2N&z.ub1e;Pri}] which are fluxional in solution at room temperature. The crystal structures of both compounds show the anion to be trigonal bipyramidal with two axial and two equatorial halides. |
