Abstract
The coordination of decamethyleuropocene to a "clamshell'' 1,2-bis(imino) acenaphthene (BIAN) ligand is accompanied by a one-electron redox process. The crystal structure of the Eu(3+) product has been determined. The complex crystallizes in the triclinic space group P-1, with a = 12.065(2), b = 15.391(3), c = 17.266(4) angstrom, alpha = 73.71, beta = 73.93(3), gamma = 81.40(3)degrees, V = 2948.3(10) angstrom(3) and Z = 2. The pyridine moiety of the clamshell ligand is not coordinated to the Eu(3+) center.
