讲座简介

The lecture focuses on the concept of dative bonding A→B where both electrons are donated from fragment A for the formation of the covalent bond. In contrast, in the electron-sharing variant of the covalent bond A-B each of the two components, A and B, contributes one electron. Distinguishing between the two bonding models is, for example, very helpful in describing the bond in carbon monoxide C≡O, which is a physically more reasonable picture than using charged atoms C-O+ that was suggested by Pauling. Dative bonding nicely explains why carbon suboxide C3O2 has a bent geometry with a bending angle of 169° where the central C atom is a divalent C(0) which bind two CO ligands (OC)→C←(CO), which is a member of the class of carbones CL2. Complexes with dative bonds are not restricted to carbon as central bond. There are other systems EL2 and complexes with two and three central moieties E2L2 and E3L3 (s. below). Recent experimental and theoretical work was carried out on heteroleptic carbones L1→C←L2 and borylones L1→B(R)←L2 and on dinitrogen complexes N2L2 with L = N2 as most prominent example N6.
