The crystal structure of bis(nitrilo)tris(methylenephosphonato)dodecaaquatrihydrohexasodium europium(III) [EuNa{sub 6}H{sub 3}(H{sub 2}O){sub 12}{N(CH_2PO_3)_3}{sub 2}] was determined; sp. gr. P1̄, Z = 2, a = 11.0801(3) Å, b = 11.5992(3) Å, c = 14.6879(4) Å, α = 70.096(3)°, β = 77.730(2)°, γ = 80.452(2)°. The coordination polyhedron of the Eu atom can be described as a distorted dodecadeltahedron (snub disphenoid), with two vertices occupied by nitrogen atoms of two phosphonate ligands and the other six vertices occupied by oxygen atoms of six PO{sub 3} groups. The chelate complex contains six five-membered rings Eu–O–P–C–N and six eight-membered rings Eu–O–P–C–N–C–P–O.
