- Abstract
The crystal structure of bis(nitrilo)tris(methylenephosphonato)dodecaaquatrihydrohexasodium europium(III) [EuNa6H3(H2O)12{N(CH2PO3)3}2] was determined; sp. gr. P1¯<inline-graphic></inline-graphic>, 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 PO3 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.
