Unique Deca- and Tetranuclear Halocuprate(I) Clusters of a Clamplike Ligand: Isolation, Structure, and Luminescence Properties



Invited for the cover of this issue is the group of Jian-Ping Lang at Soochow University, P. R. China. The cover image shows the structure containing the decanuclear chlorocuprate(I) cluster in which two stairlike [Cu5Cl5] fragments share two μ6-Cl and two μ-Cl atoms to form a unique [Cu10Cl10] cluster framework. In the background is a gate with the motto of the university “Unto a Full Grown Man”.

What is the most significant result of this study?

This research is mainly involved in the design and synthesis of one flexible multipyridine ligand and its halocuprate(I) clusters. One decanuclear cluster contains an unprecedented [Cu10Cl10] core in which two stair-like [Cu5Cl5] fragments share two μ6-Cl and two μ-Cl atoms. This flexible multipyridine ligand seems to be an excellent component for the preparation of high-nuclearity halocuprate(I) clusters. The synthetic methodology reported in this paper may be applied to the preparation of other high-nuclearity halocuprate(I) clusters with new structures and functionalities.

Is your current research mainly curiosity driven (fundamental) or rather applied?

Our research project is to develop good cluster-based catalysts for some special organic syntheses and polymerizations. For years, we have focused on the synthesis and structural chemistry of metal clusters with potential metal active sites. Therefore, our current research is mainly fundamental and dives into the lake of catalytic reactions related to organic synthesis and polymerizations that are catalyzed by some preformed multipurpose cluster-based compounds.

What other topics are you working on at the moment?

The other topics we are working on at the moment include synthesis of metallosulfide clusters and new catalysts based on coordination complexes. The former mainly involves the synthesis and structural chemistry of Mo(W)/Cu/S clusters and Mo(W)/Cu/S-based coordination polymers and their third-order nonlinear optical (NLO) properties. The latter is related to the design and development of coordination complexes with special photosensitive functional groups or potential catalytically active sites. These compounds can be employed to achieve [2+2] or [4+2] photoaddition reactions under UV irradiation or catalyze some organic reactions (e.g. C–C coupling, C–H activation) and polymerizations such as ring-opening polymerization.
