Abstract:
Pushing the limits of coordination chemistry : The most weakly coordinated silver complexes of the very weakly coordinating solvents dichloromethane and liquid sulfur dioxide were prepared. Special techniques at low temperatures and the use of weakly coordinating anions allowed structural characterization of Ag(OSO)]Al{OC(CF3)3}4], Ag(OSO)2/2]SbF6], and Ag(Cl2CH2)2]SbF6] (see figure). An investigation of the bonding shows that these complexes are mainly stabilized by electrostatic monopole–dipole interactions.
