Chemistry – A European Journal, EarlyView.A2.4Cr8Te14$A_{2.4}{\rm Cr}_{8}{\rm Te}_{14}$ (A = Rb, Cs) compounds exhibit a layered, ladder‐like Cr‐Te framework uniting structural motives of hollandite‐like and delafossite‐like phases. Alkali atoms are situated both in the interlayer space and tunnels within the Cr8Te14${\rm Cr}_{8}{\rm Te}_{14}$ framework.

European Journal of Inorganic Chemistry, EarlyView.The concept of scorpionate ligands has evolved significantly since the introduction of tris(pyrazolyl)borate. By integrating a biological supramolecular ligand scaffold with the classic scorpionate architecture, researchers have made notable strides in mimicking the active sites of nitrogenase and advancing homogeneous catalysis.
