Abstract
The crystal structure of the title compound, [YbCl2(H2O)6]Cl, was determined at 110 K. Samples were obtained from evaporated aceto-nitrile solutions containing the title compound, which consists of a [YbCl2(H2O)6](+) cation and a Cl(-) anion. The cations in the title compound sit on a twofold axis and form O-H⋯Cl hydrogen bonds with the nearby Cl(-) anion. The coordination geometry around the metal centre forms a distorted square anti-prism. The ytterbium complex is isotypic with the europium complex [Tambrornino et al. (2014 ▶). Acta Cryst. E70, i27].Entities:

| Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
