Synthesis and spectral studies of lanthanides coordination compounds based on N-(diphenylphosphoryl)benzamide. The structure of N-(diphenylphosphoryl)benzamide

Spectroscopy and structure of [LnL3bipy] and [LnL3phen] complexes with CAPh type ligand dimethylbenzoylamidophosphate

“…The relative luminescence intensities ratio 5 D 0 -7 F 2 / 5 D 0 -7 F 1 (red/orange ratio) at 298 K is equal to 4.4 for Eu1 and 4.6 for Eu2. This is comparable with values obtained for complexes of [EuL 3 bipy], [EuL 3 phen] composition with N-(diphenylphosphoryl)benzamide [16] and lower than for complexes with asymmetric coordination sphere, such as tris-(β-diketonate) europium complexes, which have red/ orange ratios ranging from 6.6 to 27 [17].…”

Lanthanide mixed-ligand complexes of the [Ln(CAPh)3(Phen)] and [LaxEu1−x(CAPh)3(Phen)] (CAPh = carbacylamidophosphate) type. A comparative study of their spectral properties

“…The Ln-O bond lengths of the (Pip)ligands are in the presumed range (Table 8). 18,19 The selected bond angles are given in Table 8. A similar difference in bond lengths was observed for the complexes with deprotonated CAPh ligands.…”

“…This fact also was confirmed for the deprotonated β-diketones structural analogues so-called sulfonylamidophosphates (SAPh). [17][18][19][20] Herein, we report not only traditional type of rare earth (RE) complexes [Ln(Pip) 3 (Phen)] (Ln = La, Ce-Nd, Sm-Lu, Y) synthesis and studies but also lanthanum doped by europium ones [La x Eu 1-x (Pip) 3 (Phen)] (x = 0.99, 0.95, 0.50). The N, P-substituted βdiketones, so-called carbacylamidophosphates (CAPh), were selected to explore the possibility of better characteristics of 20 lanthanide-centered luminescence of the complexes obtaining.…”

Synthesis, crystal structures and spectroscopic properties of cobalt(II) complexes with chelating sulfonylamidophosphate ligands

“…IR spectroscopic investigations of carbacylamidophosphates and their complexes are suitable for preliminary analysis of the coordination modes of these ligands [15,16]. Interpretation of the IR spectra of the compounds based on HL 1 and HL 2 are more complicated due to the proximity of absorption bands of n(SO 2 ) as , n(SO 2 ) s and n(PO) vibrations.…”
