چکیده
The title compound, [Eu(C(12)H(9.33)N(2)O)(3)]NO(3), was obtained by the reaction of Eu(NO(3))·3H(2)O and the Schiff base ligand 2-(2-pyridylimino-meth-yl)phenol. The Eu atom is located on a threefold rotation axis and is nine-coordinated by three tridentate Schiff base ligands in a distorted tricapped trigonal-prismatic geometry. The O atom at the phenol hydr-oxy group is partially deprotonated and the H atoms are modelled with one-third occupancy according to the space group R. Offset face-to-face π-π [centroid-centroid distance = 3.886 (3) Å] and edge-to-face C-H⋯π inter-actions are found between adjacent mol-ecules. An intra-molecular O-H⋯N hydrogen bond is also present.

The title co-crystal, [Eu(NCS)3(C18H15OP)3][Eu(NCS)2(NO3)(C18H15OP)3], contains two distinct neutral complexes. Each complex has threefold symmetry about its central Eu(3+) ion. As a result, the nitrate-containing mol-ecule contains disorder of its bidentate nitrate and two N-bound thio-cyanate anions, while the [Eu(NCS)3(OPPh3)3] complex is fully ordered. There is a weak π-π stacking inter-act...
متن کاملExtractive Properties of Tri-n-octylphosphine Oxide Towards Thorium (IV) and Europium (III) Ions in Aqueous Nitrate Media
Phosphoryl containing ligand tri-n-octylphosphine oxide (TOPO) in dichloromethane has been used as an extracting agent for tetravalent thorium and trivalent europium ions from their 1 M sodium nitrates. The equilibrium data reveal that both ions are extracted as the complexes at 1:3 metal/ligand ratio. The values of conditional extraction equilibrium constant (Kex) show the superior extract...

متن کاملHeterometallic europium disiloxanediolates: synthesis, structural diversity, and photoluminescence properties.
This contribution presents a full account of a structurally diverse class of heterometallic europium disiloxanediolates. The synthetic protocol involves in situ metalation of (HO)SiPh2OSiPh2(OH) (1) with either (n)BuLi or KN(SiMe3)2 followed by treatment with EuCl3 in suitable solvents such as 1,2-dimethoxyethane (DME) or tetrahydrofuran (THF). Reaction of EuCl3 with 2 equiv of (LiO)SiPh2OSiPh2...
