Area of Science:

• Materials Chemistry
• Inorganic Chemistry
• Solid-State Chemistry

Background:

• Vanadium chalcogenidostannates are an emerging class of materials with potential applications in electronics and catalysis.
• Organic-inorganic hybrid materials offer tunable properties by combining the advantages of both organic and inorganic components.
• The synthesis and characterization of novel 1D coordination polymers are crucial for understanding structure-property relationships.

Purpose of the Study:

• To synthesize and characterize two new one-dimensional (1D) vanadium(III) chalcogenidostannates.
• To investigate the structural features, including novel bridging modes of the chalcogenidostannate anion.
• To explore the magnetic, photocurrent response, and optical properties of the synthesized materials.

Main Methods:

• Solvothermal synthesis was employed to obtain the target compounds.
• Single-crystal X-ray diffraction was used for structural determination.
• Magnetic susceptibility measurements, UV-Vis spectroscopy, and photocurrent measurements were performed to characterize their properties.

Main Results:

• Two new 1D vanadium(III) chalcogenidostannates, [H2tepa]0.5[VIII(tepa)(μ-Sn2Q6)] (Q = S (1), Se (2)), were successfully synthesized.
• The structures feature 1D sinusoidal chains with [V(tepa)]3+ complexes bridged by [μ-Sn2Q6]4- anions in novel bridging modes.
• Preliminary studies indicated interesting magnetic, photocurrent response, and optical properties.

Conclusions:

• The study presents the first examples of organic hybrid polymeric chalcogenidostannates incorporating [V(tepa)]3+ complexes.
• The novel structural motifs and observed properties highlight the potential of these materials for further investigation.
• This work expands the library of vanadium-based chalcogenidostannates with potential functional applications.
