Multinuclear NMR study and crystal structures of complexes of the types cis- and trans-Pt(Ypy)2X2, where Ypy=pyridine derivative and X=Cl and I

Bis(ferrocenylimine)palladium(II) and platinum(II) complexes: Synthesis, molecular structures and evaluation as antitumor agents

“…On the other hand, anticancer activity of platinum(II) and palladium(II) complexes had for a long time been associated with their cis-configuration, until the first active trans-analogues were reported [17][18][19][20]. Furthermore, bulky analogues of cisplatin have been investigated against cisplatin resistant cells and gave significant cytotoxic activities [21,22].…”

Structural correlations for 1H, 13C and 15N NMR coordination shifts in Au(III), Pd(II) and Pt(II) chloride complexes with lutidines and collidine

“…Pazderski et al trans-and cis-[Pt(2,4lut) 2 Cl 2 ], [7,23] trans-and cis-[Pt(3,5lut) 2 Cl 2 ]. [7,24] We have performed elemental analysis for all others: [Au(2, [7] , being more precise than those published by some other authors (for [Au(2,4lut)Cl 3 ] and [Au(3,5lut)Cl 3 ], [19] [Au(2,6lut)Cl 3 ] [19,22] and trans-[Pt(3,5lut) 2 Cl 2 ]). [24] Far-IR and NMR measurements Far-IR spectra were measured in the 100-400 cm −1 range by a Perkin-Elmer Spectrum 2000 FT-IR spectrometer with a TGS (triglycerin sulphate) detector, using polyethylene discs; the strong Beer-Norton function was applied for apodisation.…”

These are probably rotational isomers, resulting from the restricted rotation around Pd-N or Pt-N bonds (due to the steric hindrance of ortho-positioned methyl substituents).…”

Design and Self‐Assembly of Ditopic and Tetratopic Cavitand Complexes

“…[14] The attribution of 13 was further confirmed by MALDI-TOF analyses of 13 and 11, in which the two complexes showed the same [M+K] + and [M+Na] + molecular ions. X-ray-quality crystals were obtained by slow diffusion of absolute ethanol into a solution of 13 in CH 2 Cl 2 .…”
