Conformational change induced by hydration: trans-dichlorobis[(1R,2R,3R,5S)-(-)-isopinocampheylamine]palladium(II) and trans-dichlorobis[(1S,2S,3S,5R)-(+)-isopinocampheylamine]palladium(II) hemihydrate.
The title compounds, trans-dichlorobis[(1R,2R,3R,5S)-(-)-2,6,6-trimethylbicyclo[3.1.1]heptan-3-amine]palladium(II), [PdCl2(C10H19N)2], and trans-dichlorobis[(1S,2S,3S,5R)-(+)-2,6,6-trimethylbicyclo[3.1.1]heptan-3-amine]palladium(II) hemihydrate, [PdCl2(C10H19N)2].0.5H2O, present different arrangements of the amine ligands coordinated to PdII, viz. antiperiplanar in the former case and (-)anticlinal in the latter. The hemihydrate is an inclusion compound, with a Pd coordination complex and disordered water molecules residing on crystallographic twofold axes. The crystal structure for the hemihydrate includes a short Pd...Pd separation of 3.4133 (13) A.
