Tris(3-chloro-pentane-2,4-dionato-κ(2)O,O')aluminium

Area of Science:

• Inorganic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Aluminum complexes with beta-diketonate ligands are widely studied for their diverse applications.
• Understanding the precise coordination environment and bonding in such complexes is crucial for predicting their properties.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, [Al(C(5)H(6)ClO(2))(3)].
• To characterize the coordination geometry and bonding parameters of the aluminum(III) cation within the complex.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of bond lengths, angles, and intermolecular interactions (C-H⋯Cl contacts) was performed.

Main Results:

• The aluminum(III) cation is octahedrally coordinated by six oxygen atoms from three 3-chloro-pentane-2,4-dionate ligands.
• The Al-O bond lengths were determined to be in the range of 1.8741(14)-1.8772(14) Å.
• Intermolecular C-H⋯Cl contacts were identified as a significant factor in the crystal packing.

Conclusions:

• The title compound exhibits a distorted octahedral geometry around the central aluminum ion.
• The crystal structure is stabilized by intermolecular hydrogen bonding, specifically C-H⋯Cl interactions.
• This detailed structural information contributes to the understanding of organoaluminum compounds and their solid-state behavior.
