Six cation-templated halometal complexes and C–H activation of alkylene-bridged azoles
摘要:
Six dication-templated complexes were discovered in efforts to investigate the effect of linear imidazolium-based template, 1,omega-bis(3,3 '-methylimidazolium)alkyl dibromide, on pure inorganic halometal clusters. Complexes {[C-4(Mim)(2)](Pb2I6)}(n) (1) (omega = 4), {[C-1(Mim)(2)] (Ag2I4)}(n) (2) (omega = 1), {[C-3(Mim)(2)](Ag2I4)}(n) (3) (omega = 3), and {[C-4(Mim)(2)](Ag2I4)}(n) (4) (omega = 4) possess 1-D chain architecture with different organic cations trapped in it. Compound {[C-3 '(Mim)(2)](CuBr3)} (5) (omega = 3) contains the mononuclear anion (CuBr3)(2-) and intra-molecular coupled organic cation with the formed seven-membered ring. {[C-2(Mim)(2)S-2](2)(Cu2I2)}(n) (6) (omega = 2) presents an infinite 2-D coordination polymer as the first representative polyrotaxane example featuring the biimidazolium thiolate cation ligand. All compounds were further characterized with IR spectra and thermal analysis properties.
