Bis-hexaaquasodium decaaqua-monohydrogen-hexasodium-terbium(III)-bis-(nitrilo-tris-methylenephosphonate) hexahydrate has been synthesized, and its crystal structure has been determined (sp. gr. P 2 1 / с , Z = 2). The terbium atom occupies the center of a cage consisting of two phosphonate ligand molecules, connected by six inorganic P–O–Na–O–P bridges, and a coordination polyhedron. The latter is an almost regular rhombohedron; two of its vertices, distant from the center, contain nitrogen atoms of two organic ligand molecules, and the other six vertices are occupied by oxygen atoms belonging to different PO 3 groups. The complex contains six five-membered chelating cycles Tb–O–P–C–N, six eight-membered cycles Tb–O–P–C–N–C–P–O, and six heterometallic cycles O–Tb–O–Na.
