چکیده
In the title compound, [Tb(C(7)H(4)NO(4))(3)]·2.75H(2)O, the Tb(3+) atom is coordinated by three tridentate 6-carb-oxy-pyridine-2-carboxyl-ate ligands and lies on a crystallographic threefold rotation axis. The coordination polyhedron around Tb(III) adopts a distorted tricapped trigonal-prismatic geometry. Disordered water mol-ecules with partial occupancy are also present in the crystal, one of which is associated with each of the carboxyl-ate O atoms of the complex unit.

In the title terbium coordination polymer, {[Tb(2)(C(6)H(8)O(4))(3)(H(2)O)(4)]·0.25H(2)O}(n), the Tb(III) atom is nine-coordinated, forming a TbO(9) polyhedra. Furthermore, two symmetric TbO(9) polyhedra share their edges, forming Tb(2)O(16) dimers, which are linked by adipate bridges into a layered structure. Inter-molecular O-H⋯O hydrogen bonds link these layers into a three-dimensional netwo...
