- 中文摘要: N,N’-1,2-phenylenebis(2-thienylideneimine) (PTI) can be obtained via the condensation of o-phenyle-nediamine and thiophene-2-carboxaldhyde in cyclohexane. It isomerized to its cyclic form 1-(2-thienyl-methyl)-2-(2-thienyl)benzimidazole (TMBI) readily in the presence of Fe2(CO)9. Coordination reactions of PTI with cuprous iodide and silver nitrate in acetonitrile resulted in the formation of [Cu(TMTBI)I]2 and [Ag(TMTBI)2]NO3, respectively, in which the PTI ligand had been isomerized to TMTBI. Both PTI, TMTBI, and complexes were characterized by NMR, IR, and Mass spectroscopies as well as elemental analysis. The crystal structures of TMTBI and [Cu(TMTBI)I]2 were determined by single-crystal X-ray diffraction. Crystallographic details for X-ray structures are as follows. TMTBI is crystallized in the monoclinic space group P2 1/n with a = 8.953(3), b = 9.150(1), c = 17.436(2) A,β= 93.73(2)°, and Z = 4. the final R factor was 0.050 (Rw = 0.066) for 1337 observed reflections. Complex [Cu(TMTBI)I]2 is crystallized in the triclinic space group P1 with a = 9.961(2), b = 10.825(2), c = 9.184 (2) A, α= 112.98(2), β= 110.78(2), γ= 88.71(2)°, and Z = 2. the final R factor was 0.056 (Rw = 0.057) for 2363 observed reflections.
