Description
Summary:In the title compound, (C7H11N2)[Er(H2O)8]Cl4·H2O, the asymmetric unit consists of one 4-(dimethyl­amino)­pyridinium and one octa­aqua­erbium cation balanced by four Cl- anions, and one water mol­ecule. The 4-(dimethyl­amino)­pyridinium cation is protonated at the pyridine N atom. The dimethyl­amino group (C/N/C) lies close to the plane of the pyridinium ring, making a dihedral angle of 4.5 (3)°. In the crystal, the [Er(H2O)8]3+ cations are linked via O-H...O and O-H...Cl hydrogen bonds, forming two-dimensional networks propagating in the ab plane. These networks are linked via O-H...O and O-H...Cl hydrogen bonds, forming a three-dimensional network. The 4-(dimethyl­amino)­pyridinium cations are located in the cavities and are linked to the framework via N-H...Cl, C-H...O and C-H...Cl hydrogen bonds.
