Intermolecular forces in intercluster compounds consisting of gold clusters and fullerides and in a series of model compounds C-60 center dot 2(PR3)AuCl

The intermolecular forces between triphenylphosphine ligands and fullerenes in intercluster compounds of gold clusters and fullerides and the related model compounds C-60 center dot 2(PR3)AuCl are mainly C-H/pi interactions. Modification of the para position of the phenyl rings in C-60 center dot 2(PR3)AuCl essentially influences this interaction and the resulting crystal structure.
