  1. Reaction of CoCO 3 with α,α,α′,α′-tetramethyl-1,3-benzenedipropionic acid (H 2 esp) in EtOH forms the paddlewheel-type dimer Co 2 (esp) 2 (EtOH) 2 , which hydrolyzes in MeCN to give a bowl-shaped heptacobalt coordination cluster complex; both compounds display antiferromagnetic interactions between high-spin Co( ii ) ions.
  2. A series of pentapyridyl-supported Ru(ii) complexes are synthesized and characterized using X-ray crystallography, UV-Vis, 1H NMR and cyclic voltammetry. Moreover, these monometallic species are compared with previously reported bimetallic analogues with regards to their structure and ligand substitution behavior.
  3. Zeolitic imidazolate frameworks (ZIFs) with open-shell transition metal nodes represent a promising class of highly ordered light harvesting antennas for photoenergy applications. However, their charge transport properties within the framework, the key criterion to achieve efficient photoenergy conversion, are not yet explored. Herein, we report the first direct evidence of a charge transport pathway through node-to-node communication in both ground state and excited state ZIFs using the combination of paramagnetic susceptibility measurements and time-resolved optical and X-ray absorption spectroscopy. These findings provide unprecedented new insights into the photoactivity and charge transport nature of ZIF frameworks, paving the way for theirmore » novel application as light harvesting arrays in diverse photoenergy conversion devices.« less
