Background:

• Ruthenium compounds are vital in catalysis and materials science.
• Understanding the structural properties of novel coordination complexes is essential for developing new applications.

Purpose of the Study:

• To synthesize and characterize a new ruthenium-barium coordination compound.
• To elucidate the crystal structure and bonding of dibarium micro-oxido-bis[pentachloridoruthenate(IV)] decahydrate.

Main Methods:

• Chemical synthesis using ruthenium(III) chloride and barium chloride in hydrochloric acid.
• X-ray crystallography to determine the crystal system (monoclinic, space group C2/c) and atomic arrangement.
• Analysis of bonding interactions, including hydrogen bonds and dipole-dipole interactions.

Main Results:

• Successful synthesis of dibarium micro-oxido-bis[pentachloridoruthenate(IV)] decahydrate (Ba(2)Ru(2)Cl(10)O.10H(2)O).
• The crystal structure features alternating layers of [Ru(2)Cl(10)O](4-) and [Ba(H(2)O)(7)](2+) complex ions along the a direction.
• The structure is stabilized by O-H...O hydrogen bonds and O-H...Cl dipole-dipole interactions.

Conclusions:

• The study provides the first detailed structural analysis of dibarium micro-oxido-bis[pentachloridoruthenate(IV)] decahydrate.
• The layered structure and intermolecular interactions offer insights into the compound's stability and potential properties.
• This work contributes to the fundamental understanding of ruthenium-based coordination compounds.
