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 Eu3+ 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) Å, α = 73.71, β = 73.93(3), γ = 81.40(3)°, V = 2948.3(10) Å3 and Z = 2. The pyridine moiety of the clamshell ligand is not coordinated to the Eu3+ center.

Graphical Abstract

A decamethyleuropocene complex of a “clamshell” ligand has been prepared and structurally characterized.

Notes

  1. The corresponding values for the C(1)–C(12), average N–C and average ring centroid-Eu distances are 1.482(6), 1.252(6) and 2.6195(7) Å, respectively in the Eu2+ complex (C5Me5)2Eu(DAD-t-Bu) [10].
