Ba3Li2V2O7Cl4, a new vanadate with a channel structure.

Area of Science:

• Inorganic Chemistry
• Solid-State Chemistry
• Materials Science

Background:

• Vanadate compounds are known for diverse structural motifs and potential applications.
• The synthesis and characterization of novel inorganic materials with complex structures are crucial for advancing materials science.

Purpose of the Study:

• To report the discovery and structural characterization of a new vanadate compound, tribarium dilithium divanadate tetrachloride.
• To investigate the crystal structure and atomic arrangement of Ba(3)Li(2)V(2)O(7)Cl(4).

Main Methods:

• Single-crystal X-ray diffraction was used to determine the crystal structure.
• Analysis of atomic sites, coordination environments, and structural motifs.

Main Results:

• The new compound Ba(3)Li(2)V(2)O(7)Cl(4) exhibits a channel structure.
• It is the first vanadate containing both barium (Ba) and lithium (Li) atoms.
• The structure features distinct Ba(2+), Li(+), V(5+), O(2-), and Cl(-) sites, with Li atoms forming tetrahedra and octahedra within porous layers and isolated chains.

Conclusions:

• The discovery of Ba(3)Li(2)V(2)O(7)Cl(4) expands the family of known vanadate structures.
• The unique arrangement of Li atoms in both tetrahedral and octahedral coordination within porous layers and chains offers insights into structure-property relationships.
