合成了乙酰丙酮铑, 并采用紫外、红外、核磁和质谱等手段研究了乙酰丙酮铑(Ⅲ)的化学结构特征. 结果表明: 乙酰丙酮铑属于低自旋的惰性配合物; 由于配合物中离域π键的形成, 配体羰基已不具备典型的羰基特征; 在快原子的轰击下, 乙酰丙酮铑的配位键逐一断裂, 释放出游离的乙酰丙酮, 最后形成103Rh+, 同时伴随共价键的断裂与重排; 在磁场中, 由于Rh3+的强吸电子效应以及螯合环的环电子流效应, H核化学位移向低场移动. 通过TG-DTA和GC-MS分析并探讨了乙酰丙酮铑的热分解行为, 为其应用提供了热学依据和理论参考, 并建议以300.℃作为以乙酰丙酮铑为前驱体的CVD铑沉积工艺的沉积温度.
