Bis(chlorido)(dimethyl-sulfoxide-κO)barium(II).

Area of Science:

• Inorganic Chemistry
• Crystal Engineering
• Materials Science

Background:

• Barium chloride (BaCl2) is a common inorganic salt.
• Dimethyl sulfoxide (DMSO) is a versatile polar aprotic solvent.
• Understanding the coordination chemistry of metal halides with organic ligands is crucial for designing novel materials.

Purpose of the Study:

• To synthesize and characterize a novel barium chloride-dimethyl sulfoxide compound.
• To elucidate the structural features of the resulting barium-containing cluster.
• To investigate the supramolecular assembly of these clusters in the solid state.

Main Methods:

• Single-crystal X-ray diffraction was used to determine the molecular and crystal structure.
• Chemical synthesis involving barium chloride and dimethyl sulfoxide was performed.
• Analysis of coordination environments and bridging motifs within the crystal lattice.

Main Results:

• The title compound, [BaCl2(C2H6SO)], crystallizes as a Ba(6)Cl(9) cluster.
• Barium chloride units are bridged by dimethyl sulfoxide (DMSO) and chloride ligands.
• A central chloride atom is octahedrally coordinated to six barium cations within the cluster.
• Clusters are arranged in rows interconnected by DMSO molecules, forming a 3D network.

Conclusions:

• A novel Ba(6)Cl(9) cluster compound incorporating DMSO has been successfully synthesized and characterized.
• The structure reveals a unique coordination environment around the central chloride atom.
• The interconnected cluster arrangement highlights the role of DMSO in mediating supramolecular assembly.
