| Abstract: | Two new Re(III) and Re(IV) complexes with 2(2′-pyridyl)benzimidazole (pbimz) were prepared and their crystal and molecular structures established by single-crystal X-ray diffraction. Reaction of ReOCl2(OEt)(PPh3)2] with the ligand gave red cis(Cl),trans(P)-ReCl2(PPh3)2(pbimz)]Cl (1), while red ReCl4(pbimz)] · OPPh3 (2) was obtained from ReCl3(PhC(O)C(O)Ph)(PPh3)] and pbimz in the presence of perchlorate. The compounds were characterized by elemental analysis, FAB-MS, UV-Vis, IR, NMR spectroscopy and magnetic susceptibility measurements. |
