Abstract:
Systematic dimensional regulation of low-dimensional metal halides remains challenging for establishing clear dimension-property relationships because changes in dimensionality are often accompanied by variations in chemical composition or inorganic building units. Herein, we realize systematic dimensionality regulation across 0D (DMP)2Cu2Cl6, 1D (DMP)Cu2Cl4, and 2D (DMP)Cu2Cl4 through a solvent-mediated structural engineering strategy, while preserving the same organic cation and local [Cu2Cl6] dimer building unit. This homologous series enables a more direct correlation between framework connectivity and structural and photophysical properties, including Cu···Cu contacts, band gaps, and photoluminescence associated with self-trapped excitons. The three compounds exhibit distinct Cu···Cu contacts and emission profiles, highlighting the influence of structural dimensionality and local coordination environments on their photoluminescence behavior.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
