Abstract

A carbohydrate-derivative alkylcobalt carbonyl, {[(1,2:5,6-di-O,O-isopropylidene-alpha -D-glucofuranos-3-yl) oxycarbonyll methyl I cobalt tricarbonyl triphenylphosphine (3) was prepared and characterized by IR, NMR, and CD spectra, as well as by X-ray diffraction. The supramolecular chemistry in the crystalline P2(1)2(1)2(1) (chiral) phase and in solution was analyzed and compared. The bulky carbohydrate-based ligand stabilized one chiral conformation, which, however, is less ordered than for analogous compounds with more flexible and less bulky chiral groups. Intermolecular, H-bond interactions are more important in the P2(1)2(1)2, phase of complex 3 than at other analogous compounds.
