SYNTHESIS AND CRYSTAL STRUCTURE OF [Rh2(CH3COO)4(N-BuIm)] COMPLEX

Abstract

This complex was synthesized following by the method described elsewhere [1]. To a solution of [Rh2(CH3COO)4(H2O)2] (0.0478 g, 0.10 mmol) in toluene (10 mL) the N-butylimidazole (0.0290 mL, 0.22 mmol) was added. The resulting mixture was stirred at room temperature for 1 hour until the reagents were completely dissolved. The solution was left at room temperature to evaporate slowly to a volume of ~ 5 mL and then stored overnight in the refrigerator. The precipitated purple crystals were filtered off under vacuum and washed with toluene and diethyl ether. The obtained crystals represent a complex of [Rh2(CH3COO)4(N-BuIm)].
