Abstract:
The structure of the complex [{Pb(HBpz3)}{Au3(o-C6BrF4)3(HBpz3)}] consists of a host-guest heterometallic system built up through a plethora of interactions including electrostatic, metallophilic, H-bonding, AuBr or weak CC or PbBr contacts. Computational studies show that the dispersive interactions are responsible for the attraction of the Pb(ii) cationic moiety within the basket-like trinuclear Au(i) fragment, whereas the ionic component of the interaction placed at the rings produces a molecular clamp.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
