Syntheses, structures, and reactions of rhenium and ruthenium carbonyl derivatives of 2,2′-bis(indenyl)propane.

Highlights: [•] Two pairs of rac- and meso-diastereomers were successfully separated. [•] Photolysis of (CMe2)(C9H7)(η 5-C9H6)Re(CO)3 (1) yielded the novel product (CMe2)[(η 5-C9H6)(η 2-C9H7)]Re(CO)2 (3). [•] Molecular structures of all compounds were determined by X-ray diffraction.
