The complex was found to have the 2,6-diaminopyridine ligand bonded to the chromium atom through one of the NH2 groups. A single crystal X-ray structure of the complex reveals that the coordination sphere around the chromium atom is a slightly distorted octahedron, involving five carbonyls and one 2,6-diaminopyridine ligand. Because of the steric requirement of 2,6-diaminopyridine the four equatorial carbonyl groups are bended away from the N-donor ligand. The pyridine plane makes an angle of 112.9(3)degrees with the OC-Cr-N bond axis. The Cr-C distances have values between 1.833(7) and 1.935(7) Angstrom. The Cr-N distance is 2.236(5) Angstrom.eninfo:eu-repo/semantics/closedAccessChromiumCarbonylDiaminopyridineMolecular StructureXRDX-ray diffractionSynthesisPhotolysisSpectroscopic TechniquesArticle10.1016/j.jorganchem.2004.04.02068914231923232-s2.0-2942687020Q3WOS:000222416800006Q2
