| Abstract: | The existence and characterization of cis and trans isomers of Pd(NH3)2Cl2 have been re-investigated. A stable monoclinic trans compound has been prepared at low temperature. It has been shown that when trans-Pd(NH3)2Cl2 is prepared at room temperature or above, it is a mixture of monoclinic and tetragonal dimorphs. The material previously reported to be cis-Pd(NH3)2Cl2 has been shown to be a complex mixture while the pure authentic cis-Pd(NH3)2Cl2 has been prepared and identified by its unique X-ray diffraction pattern and infra-red spectrum. |
