Layer Geometry Modulation in Cu(II) Coordination Networks Based on Disubstituted Bis(imidazolyl)benzene Ligands

European Journal of Inorganic Chemistry, EarlyView.
Cu(II)‐based two‐dimensional coordination networks constructed from bis(imidazolyl)benzene ligands show how subtle changes in counteranion identity modulate layer geometry, stacking, and stability. Single‐crystal structures combined with bulk syntheses reveal distinct packing efficiencies and framework responses to humidity, vacuum, and temperature for

Dilithium Enediamide Derived From a 1,4‐Diaza‐1,3‐diene: Reactivity of a Strongly N‐Basic, Highly C‐Nucleophilic Compound Toward C–H Acids

European Journal of Inorganic Chemistry, EarlyView.
The lithium enediamide complex 2 with intrinsically inverted C–N bond polarity combines strong basicity with unusual reactivity: deprotonation of malonates enables C–C bond formation without electron transfer. Depending on malonate substitution, electrophilic substitution or addition occurs at the enediamide CC bond.

Dilithium Enediamide Derived From 1,4‐Diaza‐1,3‐Diene: An Electron Reservoir Enabling Variable Reactivity Toward Carbonyl Compounds

European Journal of Inorganic Chemistry, EarlyView.
Upon reduction of 1,4‐diaza‐1,3‐diene 1 to the dilithium enediamide 2, the polarity of the C = N bonds is reversed ‐ a classic case of umpolung. This behavior is particularly evident in reactions of the dianion 2 with carbonyl compounds and also explains why 1,4‐diaza‐1,3‐diene ligands do not always act merely as spectator ligands. 1,4‐Diaza‐1,3‐dienes

Actinide 4,4′‐Bipyridine‐N,N′‐Dioxide Coordination Polymers: Cationic Framework Structures Templated by Dicyanoaurate and Tetracyanoaurate Counterions

European Journal of Inorganic Chemistry, EarlyView.
Th4+ or UO22+ actinides, neutral bipyridine‐N,N’‐dioxide ligands, and anionic cyanoaurate linkers are combined to generate a family of four coordination polymers. ‘Truss bridge’ and square grid cationic frameworks are yielded when using [Au(CN)2]− or [Au(CN)4]−, respectively, indicating a templating effect guided by either aurophilic interactions ...

Tuning the Electronic Structure and Photocatalytic Properties in Polar Two‐Dimensional Gallium Oxide Through Interlayer Stacking and Sulfur Doping

Electron, EarlyView.
This work demonstrates that site‐selective sulfur doping effectively narrows the bandgap of polar 2D Ga2O3 monolayer while preserving the built‐in electric field, enabling efficient carrier separation and enhanced visible‐light absorption for photocatalytic water splitting.
