Abstract

One of the advantages of coordination complex with a framework structure is that it facilitates conducting metal exchange reaction or transmetallation, which important for several purposes. In this study, we evaluated transmetallation phenomena in a 116 nuclear complex of [{Au6Cd3(tdme)2(D-pen)6}12Cd4Na4](NO3)12 (1CdNa) using monovalent and divalent metal ions from alkali and alkaline-earth groups, respectively. The metal replacements were carried out in high concentration solution through single-crystal-to-single-crystal manner. The observation focused on the structural refinement based on single-crystal X-ray diffraction data. The results indicated that selective metal exchange occurred exclusively in specific locations. The presence of d-orbital and metal coordination preferences became two pivotal factors to proceed transmetallation in 1CdNa.
