(3E,5E)-3,5-Bis(2-chloro­benzyl­idene)-1-propyl­piperidin-4-one

The title compound, C₂₂H₂₁Cl₂NO, is a derivative of mono-carbonyl analogues of curcumin (MACs). The mol­ecule has an E conformation for each of the olefinic bonds. The 1-propyl­piperidin-4-one ring has a distorted chair conformation with the ring N and the C and O atoms of the carbonyl group deviating from the mean plane of the remaining four ring C atoms by 0.682 (2), −0.134 (3) and −0.340 (4) Å, respectively. The dihedral angle between the benzene rings is 26.5 (1)°. In the crystal, mol­ecules are connected by weak C—H...O and C—H...π inter­actions.

Tris(diisopropyl di­thio­phosphato-κ²S,S′)ruthenium(III)

In the title complex, [Ru(C₆H₁₄O₂PS₂)₃], the coordination environment of the Ru^III atom is distorted octa­hedral, defined by six S atoms from three S,S′-bidentate diisopropyl di­thio­phosphate ligands. The average Ru—S bond length is 2.41 (1) Å and the average S—Ru—S bite angle is 81.13 (19)°.
