synthesized from the design of ellipticine showed activity in the course of preliminary study on mouse leukemia P388. In light of the properties and crystal structure of [ethidium]2 PtCl4 (1) and of [rhodamine123]2 PtCl4.H2O (2), the firsttetrachloroplatinate (II) with anticanceractivity, we attempt to synthesize an analogous complex salt by replacing the rhodamine cation by the protonated DPC molecule (DPCH+)
