Abstract: Using rhodium(Ⅱ) acetate and trimethylrhodium acetate(Ⅱ) as the raw material,with 3,6-dibromo-9-(4-pyridinemethyl)-9H-carbazole (DBPMC1) and 3,6-dibromo-9-(3-pyridinemethyl)-9H-carbazole (DBPMC) as axial ligands,four rhodium(Ⅱ) carboxylates axial dibromo-9-pyridylmethyl-9H-carbazole complexes Rh(OOCR)4(DBPMC) were designed and synthesized.The single crystals of compounds were successfully cultured and their chemical structures were initially characterized by modern analytical methods such as H NMR,13C NMR and FT-IR.The results show that none of these four compounds has been reported in the literature,and they belong to a new type of rhodium carboxylate (Ⅱ) axial complex.The structure of the complex was determined by X-ray single crystal diffraction analysis to be composed of one molecule of rhodium(Ⅱ) carboxylate and two molecules of DBPMC ligand,and the molecular structure diagram and unit cell stacking diagram were drawn.

Key words: rhodium(Ⅱ) acetate, axial coordination, crystal structure, molecular structure diagram, cell stacking diagram
