Abstract
Bis-hexaaquasodium decaaqua-monohydrogen-hexasodium-terbium(III)-bis-(nitrilo-tris-methylenephosphonate) hexahydrate has been synthesized, and its crystal structure has been determined (sp. gr. P21/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 PO3 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.
