WebMolecular structure analyses indicated that, in complex 1, the two –OPh groups of two [LOPh(SQ)]–ligands are situated transto each other, while in complex 2, the two –SPh groups of two [LSPh(SQ)]–ligands were found to maintain a cisrelationship. WebAn electron donating group ( EDG) or electron releasing group ( ERG, Z in structural formulas) is an atom or functional group that donates some of its electron density into a conjugated π system via resonance (mesomerism) or inductive effects (or induction)—called +M or +I effects, respectively—thus making the π system more nucleophilic.
