Abstract
In the title terbium coordination polymer, {[Tb2(C6H8O4)3(H2O)4]·0.25H2O}n, the TbIII atom is nine-coordinated, forming a TbO9 polyhedra. Furthermore, two symmetric TbO9 polyhedra share their edges, forming Tb2O16 dimers, which are linked by adipate bridges into a layered structure. Intermolecular O—H⋯O hydrogen bonds link these layers into a three-dimensional network. One of the C atoms of the adipate ligand is disordered over two positions with site-occupancy factors of 0.622 (9) and 0.378 (9). The structure also contains a disordered molecule of water of hydration, lying close to a special position, with partial occupancy.
