Cerium suboxide clusters are a recent catalyst class that has received interest for the generation of H<sub>2</sub> from water. Using density functional theory calculations, this work examines the reaction of Ce<sub>2</sub>O<sup>–</sup> clusters with H<sub>2</sub>O. It is shown that the reaction can proceed along both doublet and quartet pathways. In both cases, hydrogen formation is facilitated by intermediate structures featuring bridging hydride and hydroxide ligands. Interestingly, it is shown that metal d electrons facilitate the reduction of water. This work provides new understanding of this reaction and provides new insight into the reactivity of small lanthanide-based clusters with water.<br>

Copper(II) benzoates ([Formula: see text]OBA-Cu) with various terminal alkoxy carbon numbers, [Formula: see text]–12, were prepared from [Formula: see text]-[Formula: see text]-alkoxy benzoic acids (nOBAs). Fourier transform infrared (IR) experiments suggested that dimerization through copper(II) chelating bidentate coordination created [Formula: see text]OBA-Cu with a linear rod-like structure, similar to the hydrogen-bonded structure of its parent [Formula: see text]OBA. However, the coordination structure of [Formula: see text]OBA-Cu changed during heating. Periodic density functional theory calculations provided valuable insight into the possible arrangement of the parent and copper(II)-coordinated [Formula: see text]OBAs. The formation of binuclear complexes between two adjacent [Formula: see text]OBA-Cu dimers forced [Formula: see text]OBA-Cu to arrange itself in a layer and exhibit smectic A mesophase. Accordingly, four types of IR stretching absorption of benzoyl carbonyl were observed in binuclear [Formula: see text]OBA-Cu complexes, replacing the original symmetric and asymmetric vibrations of benzoyl carboxylate in chelating bidentate coordination. The lateral association by [Formula: see text]–[Formula: see text] interactions between adjacent parent [Formula: see text]OBA dimers preferred a progressive smectic C arrangement. The origin of the odd–even effect was understood from the consideration of the molecular structure.
