catena-Poly[(S)-2-methyl-piperazine-1,4-diium [[trichloridobismuthate(III)]-di-μ-chlorido]]

Area of Science:

• Inorganic Chemistry
• Crystal Engineering
• Materials Science

Background:

• Bismuth(III) chloride complexes are known for diverse structural motifs.
• Polymeric coordination compounds offer tunable properties.
• Hydrogen bonding plays a crucial role in supramolecular assembly.

Purpose of the Study:

• To elucidate the crystal structure of a novel bismuth(III) complex.
• To investigate the coordination environment and bonding interactions.
• To understand the self-assembly mechanism of the inorganic-organic hybrid structure.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed.
• Structural characterization involved determining atomic coordinates and bond lengths/angles.
• Intermolecular interactions, including hydrogen bonding, were analyzed.

Main Results:

• The crystal structure features a zigzag polymeric chain of [BiCl5] units along the a axis.
• Bismuth(III) exhibits a distorted octahedral coordination geometry.
• The methylpiperazinediium cation adopts a chair conformation and links chains via N-H⋯Cl hydrogen bonds.

Conclusions:

• A novel 1D coordination polymer based on bismuth(III) and chloride has been synthesized and characterized.
• The structure highlights the interplay between inorganic coordination and organic cation interactions.
• This work contributes to the understanding of bismuth halide-based materials and supramolecular chemistry.
