Platinum(II) and palladium(II) complexes with (N,N′) and (C,N,N′)− ligands derived from pyrazole as anticancer and antimalarial agents: Synthesis, characterization and in vitro activities
pzol represents pyrazole and RH (1a), Me (1b) or Ph (1c)} with [MCl2(DMSO)2] (MPt or Pd) under different experimental conditions allowed us to isolate and characterize cis-[Mκ2-N,N′-[1-(CH2)2NMe2}-3,5-R2-pzol])}Cl2] MMPtPt (2a–2c) or Pd (3a–3c)} and two cyclometallated complexes [Mκ3-C,N,N′-[1-(CH2)2NMe2}-3-(C5H4)-5-Ph-pzol])}Cl] MPt(II) (4c) or Pd(II) (5c)}. Compounds 4c and 5c arise from the orthometallation
