In contrast to the Co-O centers, the Co-Br tetrahedra exhibit only minor deviations from the initial four-fold coordinated state caused by the high temperature. This persistence of the tetrahedral state is found to be independent of the water content (Figure ). Figure illustrates the movement of a water molecule inside the structure at 1000 K, highlighting how water explores multiple parts of the structural space, including both the Co-O octahedra as well as the Co-Br tetrahedra.
