Summary
This study details the crystal structure of a chromium(III) complex with 1,10-phenanthroline (phen) ligands. The complex exhibits a distorted octahedral geometry around the central chromium atom.
Area of Science:
- Inorganic Chemistry
- Coordination Chemistry
- Crystallography
Background:
- 1,10-phenanthroline (phen) is a versatile bidentate ligand commonly used in coordination chemistry.
- Chromium complexes are of interest due to their diverse applications in catalysis and materials science.
Purpose of the Study:
- To elucidate the detailed crystal structure of the [Cr(phen)3](ClO4)3.H2O complex.
- To characterize the coordination environment and bonding parameters of the chromium center.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Structural analysis involved bond length and angle measurements, and assessment of coordination geometry.
Main Results:
- The cation features a central chromium(III) ion coordinated to three 1,10-phenanthroline ligands.
- A distorted octahedral geometry was observed around the chromium atom, with Cr-N bond distances ranging from 2.040 to 2.055 Å.
- One perchlorate anion exhibited disorder, occupying two crystallographic positions.
Conclusions:
- The structural data provides fundamental insights into the coordination behavior of chromium with 1,10-phenanthroline.
- The findings contribute to the understanding of structural variations in octahedral chromium complexes.
