Hetero-topic self-assembly of Re2(CO)10 with oxamide ligands and ester-functionalised flexible ditopic-tectons afforded dinuclear metallacycles resembling a stirrup. The metallastirrups showed promising cytotoxic activity against few cancer cell lines
Flexible dimanganese metallacycles have been achieved using Mn(CO)5Br and adaptable ditopic pyridyl linkers. The host–guest chemistry of Mn(
