“…This may be rationalized in terms of a strong attractive interaction between P dþ eO dÀ . Similar contacts were also found in some of the carbacylamidophosphate ligands [41]. There is also an intramolecular electrostatic interaction between O(2) of C]O group and N(1) atom with the O/N distance of 3.048 Å.…”

“…Moreover, (P-N) shifts to higher wavenumbers from 919 cm À1 for (2) to 1039 and 1040 cm À1 for (7) and (8), respectively, consistent with the strengthening of the P-N bond in the complexes (Gholivand, Mahzouni, Pourayoubi & Amiri, 2010;Gubina et al, 2009). Furthermore, the (N-H) values increase in (7) and (8), presumably owing to the participation of the N-H group in different hydrogen bonds in the ligand and complexes (Gholivand, Mahzouni, Pourayoubi & Amiri, 2010).…”

In this study, the synthesis and spectroscopic characterization of new phosphoramides based on 3-amino-5-methylisoxazole with the formula R2P(O)[NH-C4H4NO], R = C6H5O (1), C6H5 (2), RP(O)[NH-C4H4NO]2, R = C6H5O (3), CH3-C6H4O (4), C6H5NH (5), (C6H5)ClP(O)[NH-C4H4NO] (6) and two lanthanide complexes [Ln(2)2(NO3)3(EtOH)]·EtOH, Ln(III) = Ce (7) and Eu (8), have been reported. The structural study of (3) shows the presence of two conformers (crystallographically independent molecules) in the crystalline lattice, caused by different orientations of the phenyl and isoxazole rings. For (3), the intermolecular interactions have been studied by Hirshfeld surface analysis and fingerprint plots. Furthermore, the electronic and energy aspects of hydrogen bonds between molecules of (3) have been explored by density functional theory (DFT) calculations. X-ray crystallography of complexes (7) and (8) reveals that two phosphoramide ligands take part in coordination to the metal, one as monodentate from O(phosphoryl), and the other one as chelate through O(phosphoryl) and N(ring). The complexes are also composed of two conformers in the solid-state structure. Quantum theory of atoms in molecules (QTAIM) analysis discloses the electrostatic nature of the Ln-ligand interaction.

“…The spectrum of the complex is similar to the eight-coordinate Nd(III) chelate. Judging from the spectra, the arrangement of effective charges in the surroundings of Eu(III) ions in all doped complexes is noncentrosymmetric with low symmetry of crystal 25 field. A whole series of complexes has the highest maximum excitation wavelength at about 340 nm.…”

“…24 As it was shown in the previous investigations, the neutral form of CAPh coordinates 15 mostly in a monodentate manner via the oxygen atom of the phosphoryl group whereas the deprotonated form in a bidentate manner via the oxygen atoms of the phosphoryl and carbonyl groups forming six-membered chelate cycles.

“…1B) implies that it could be resulted by an overlap of at least two bands at very close 30 frequencies. 19,25 The vibration bands of the 1,10-phenanthroline ligand in the IR spectra of the coordination compounds are either overlapped by the bands of the CAPh ligands and have low intensities. As it was already mentioned, the structures of 1, 2 and 3 revealed different geometrical parameters of coordinated carbacylamidophosphate chelate rings 35 within one molecule.…”

A series of complexes Ln(Pip)3(Phen) (Ln(iii) = La, Ce-Nd, Sm-Lu, Y; HPip (CAPh type ligand) = 2,2,2-trichloro-N-(dipiperidin-1-yl-phosphoryl)acetamide, Phen = 1,10-phenanthroline) has been synthesized. The lanthanum(iii) doped europium(iii) complexes ([LaxEu1-x(Pip)3(Phen)], x = 0.99, 0.95, 0.50) have been obtained by the co-crystallization method. The complexes have been characterized by means of X-ray diffraction, IR, (1)H and (31)P-NMR and absorption spectroscopy. Emission and excitation luminescence spectra were recorded at 295 and 77 K. The lifetime values (τ) for the emission of all europium complexes were determined. The (5)D0 luminescence quantum efficiency is 73-89%. The symmetries of the nearest europium surrounding in pure and doped complexes were evaluated from the Stark splitting of (5)D0-(7)FJ transitions. Crystal structures of [Ln(Pip)3(Phen)] (Ln = Nd (1), Eu (2) and Tb (3)) have been determined. Lattice parameters of the [Ln(Pip)3(Phen)] (Ln = Tb, Yb) and the doped [LaxEu1-x(Pip)3(Phen)] (x = 0.99, 0.95, 0.50) complexes have been measured. The presence of four polymorphs within a number of rare earth elements has been estimated: two in triclinic (Ln1 = La, Nd; Ln2 = Eu), one in the monoclinic (Ln3 = Tb) and one in the rhombic (Ln4 = Tb, Yb) symmetry. Complex 3 can be obtained in two crystal modifications: monoclinic and orthorhombic ones.
