Matrinium tetra­chloro­ferrate(III)

The title compound, (C₁₅H₂₅N₂O)[FeCl₄], consists of one matrinium cation {matrine is (7aS,13aR,13bR,13cS)-dodeca­hydro-1H,5H,8H-dipyrido[2,1-f:3′,2′,1′-ij][1,6]-naphthyridin-10-one} and one [FeCl₄]⁻ anion. One ring of the matrinium cation has a half-chair conformation, whereas the others have chair conformations. Chiral chains of the title compound are formed by C—H...O and N—H...O hydrogen bonds.

Aqua­dichloro­bis(2-chloro­pyridine-κN)copper(II)

In the title compound, [CuCl₂(C₅H₄ClN)₂(H₂O)], the Cu^II atom is coordinated by one water mol­ecule, two Cl⁻ ions and two 2-chloro­pyridine mol­ecules. The structure is built up via O—H...Cl hydrogen bonds and stablized by π–π stacking and Cl...Cl inter­actions.
