Europium-doped barium bromide iodide.

Area of Science:

• Solid-state chemistry
• Crystallography
• Materials science

Background:

• Barium europium bromide iodide (BaEuBrI) is a halide compound.
• Understanding its crystal structure is crucial for potential applications.

Purpose of the Study:

• To grow single crystals of Ba(0.96)Eu(0.04)BrI.
• To determine the crystal structure and cation coordination of the title compound.

Main Methods:

• Single crystal growth via the Bridgman technique.
• Crystallographic analysis to determine structure and atomic positions.

Main Results:

• Successfully grew single crystals of Ba(0.96)Eu(0.04)BrI.
• The compound crystallizes in the ordered PbCl(2) structure, space group Pnma.
• Ba and Eu atoms are statistically distributed on the 4c sites.
• Cations exhibit a tricapped trigonal prismatic coordination with nine anions.

Conclusions:

• The Bridgman technique is suitable for growing BaEuBrI single crystals.
• The determined crystal structure provides a basis for further investigation of its properties.
