Abstract

The title compound, (C7H11N2)3[Nd2Cl4(H2O)10]Cl5·2H2O, consists of three 4-(dimethylamino)pyridinium cations, one of which is disordered about an inversion center, one [Nd2Cl4(H2O)10]2+ dication possessing inversion symmetry, five chloride anions, one of which is disordered over two inversion centers, and two lattice water molecules. The 4-(dimethylamino)pyridinium cations are protonated at the pyridine N atoms and form N—H⋯Cl hydrogen bonds with Cl− counter-ions. The dimethylamino groups (C/N/C) lie close to the plane of the pyridinium rings, making dihedral angles of 1.6 (6)° and 6.5 (3)°. In the crystal, the [Nd2Cl4(H2O)10]2+ dications are linked via O—H⋯O and O—H⋯Cl hydrogen bonds, forming sheets lying parallel to the bc plane. These sheets are linked via O—H⋯Cl hydrogen bonds, forming a three-dimensional network. The 4-(dimethylamino)pyridinium cations are located in the cavities and linked to the framework by C—H⋯Cl interactions.
