Crystal structure of [p-C6H4(CH2ImMe)2][PtCl6]

Area of Science:

• Inorganic Chemistry
• Crystal Engineering
• Coordination Chemistry

Background:

• Understanding the supramolecular assembly of ionic compounds is crucial for designing novel materials.
• Hexachloroplatinate anions and imidazolium cations are common building blocks in coordination chemistry.
• Intermolecular interactions, such as hydrogen bonding, play a significant role in crystal structure determination.

Purpose of the Study:

• To elucidate the crystal structure of the complex formed between a specific bis(imidazolium) dication and the hexachloroplatinate anion.
• To investigate the nature and role of intermolecular interactions in the self-assembly of this ionic complex.
• To characterize the coordination geometry around the platinum center.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of bond distances, bond angles, and intermolecular contacts was performed.
• Computational methods may be used for further analysis of electronic structure and bonding (if applicable, though not explicitly stated in the abstract).

Main Results:

• The crystal structure comprises discrete [p-C6H4(CH2ImMe)2]2+ dication and [PtCl6]2- anion pairs.
• The platinum atom exhibits hexacoordination with six chloride ligands, adopting an octahedral geometry.
• The average Pt-Cl bond distance was determined to be 2.3199 Å.
• Hydrogen bonding interactions were observed between the imidazolium cation and the hexachloroplatinate anion.
• Crystal packing is predominantly influenced by CH...Cl interactions.

Conclusions:

• The study successfully determined the crystal structure of the title complex.
• The observed hydrogen bonding and CH...Cl interactions are key factors governing the crystal packing.
• This structural information provides insights into the supramolecular chemistry of platinum complexes with organic cations.
