A view of the crystal structure excluding the propionate methylene and methyl groups as well as the disordered propionic acid molecule. Ba—O—Ba bonds and O—H⋯O bonds [except for O16⋯O4vii (−x + 1, −y, −z + 1) where the bridging hydrogen atom was not found] are displayed. For colour codes, see caption for Fig. 1. |
