M 2 L 4 Complexes for the Targeted Drug Delivery of Cisplatin and N-heterocyclic Silane and Silylene Pyridine chelates – findings on the way to novel noble metal catalysts

New molecular M 2 L 4 cages for the targeted drug delivery of cisplatin in tumor cells are presented. These complexes are capable of encapsulating cisplatin and hereby enhance its effectiveness against cancer cells. Furthermore, a new ambidentate N-heterocyclic silane ligand is reported, which forms novel complexes with iridium and rhodium salts. For rhodium, this leads to a yet unprecedented, electronically induced coordination change.
