Crystal structure of chlorido­(piperidine-κN)(quinoline-2-carboxyl­ato-κ²N,O)platinum(II)

The platinum(II) complex with notable antitumor activity shows a slightly distorted square-planar coordination and intramolecular C—H...Cl and intermolecular N—H...Cl and C—H...O hydrogen bonds.

Open access is good for you!

Crystal structure of (1Z)-1-(4-chloro­benzyl­idene)-5-(4-meth­oxy­phen­yl)-3-oxopyrazolidin-1-ium-2-ide

The planar pyrazolidine ring occurs in the betaine form with a Z conformation of the exocyclic C=N bond. In the crystal, C—H...O and C—H...π inter­actions result in the formation of ribbons of mol­ecules along [10].

Crystal structure of chlorido­{4,5-dimeth­oxy-2-[(2,3-η)-2-prop-2-en-1-yl]phenyl-κC¹}(piperidine-κN)platinum(II) ethanol monosolvate

The title platinum(II) complex shows a trigonal–bipyramidal coordination and inter­molecular C—H...Cl, C—H...π and (C/O)—H...O hydrogen bonds.
