Chirality at metal centers

In a recent review on predetermined chirality at metal centers, Khof and von Zelewsky described the chiral quadruply bonded species A and A-[Mo2Cl4(5,5-dppb)2] (where dppb = 2,3-bis(diphenylphosphino)butane) as M-configurational double helices. Such twisted multiply bonded complexes are paradigm examples of intrinsically chiral chromophores where the chiral center is not located at the metal atom but embraces the whole twisted M02X4P4 unit. The CD spectra of a range of chiral quadruply bonded compounds, with a variety of bidentate and monodentate chiral ligands (phosphines and amines) have been reported and can be explained by a simple metal localized theory. ... [Pg.74]
