Abstract:
Chalcogenidostannates possess diverse properties that are promising for various applications. Under solvothermal conditions, we synthesized two new compounds: Rb6Cd4Sn3Se13 (1) and [Eu(trien)(tren)Cl]Hg2SnSe5 (2) (trien = triethylenetetramine; tren = tris(2-aminoethyl)amine). Compound 1 features a 3D anionic framework with Rb+ cations containing a large 18-membered ring. Compound 2 exhibits a double-chain anionic structure separated by the [Eu(trien)(tren)Cl]n2n+ complexes. Both Rb+ and the lanthanide complex act as distinct structure-directing agents, significantly influencing the final architectures. Both compounds demonstrate excellent photocurrent responses (ca. 12.6 μA/cm2 for 1; ca. 129.3 μA/cm2 for 2) and were evaluated for photocatalytic methylene blue (MB) degradation. Theoretical calculations elucidated the optical-electronic structure relationships. Crucially, 1 exhibits superior Cs+/Sr2+ ion-exchange capability and a powder second-harmonic generation (SHG) response ∼0.38 times that of AgGaSe2 (150-200 μm particles).

02:34Structural 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...
02:52Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

02:42Ionic 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...
02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
