Abstract
Remarkable differences are observed in the molecular structures of Zn(S2COCH2Ph)2(dafone) (1) and Cd(S2COCH2Ph)2(dafone) (2); where dafone is 4,5-diazafluoren-9-one-N,N′. In 1, an S,O mode of coordination of one of the xanthate ligands is observed, an orientation that facilitates the formation of intramolecular π…π interactions between the benzyl and dafone rings. The second xanthate ligand coordinates in an S,S mode and the dafone ligand is chelating. The resulting N2OS3 donor set defines a distorted octahedral coordination geometry. A similar geometry is found in 2 but based on an N2S4 donor set. Despite the different molecular structures, the global crystal packing patterns for 1 and 2 are almost identical, comprising layers.
