The heterobinuclear isomers [
6-(2-ferrocenyl)indene]-Cr(CO)3 (1) and [6-(3-ferrocenyl)indene-Cr(CO)3 (2) have been prepared and the crystal structuredetermination showed that the Fe(C5H5) and Cr(CO)3groups in the two molecules are disposed in differentconformations with respect to the Cp-indene bridgingligand, cisoid in 1 and transoid in 2. Preliminaryelectrochemical (CV) and spectroscopic (IR and near-IR)results obtained for the corresponding monooxidized 1+and 2+ demonstrate the existence of stronger electroniccoupling in 1+ than in 2+.
