Triphenylphosphane Oxide Complexes of Lanthanide Nitrates: Polymorphs and Photophysics

“…The isomorphic series, 2 , is also monoclinic ( P 2 1 / c, a = 14.6 Å, b = 18.4 Å, c = 20.6 Å, β = 102°). Prior to this work, two examples of 2 had been reported, Ln (NO 3 ) 3 (Ph 3 PO) 3 ( Ln = Nd and Sm) , . Neither of these complexes were reported as solvates, having been crystallized from ethanol.…”

“…Numerous solvent‐free Ln (NO 3 ) 3 (Ph 3 PO) 3 complexes have also been structurally characterized for Ln = Y, La, Pr, Nd, Sm, Gd, and Eu , , , . Polymorphism is clearly an important factor in these series of complexes, given the fact that two polymorphs each have been identified for Nd(NO 3 ) 3 (Ph 3 PO) 3 ,, and Gd(NO 3 ) 3 (Ph 3 PO) 3 . In this article, we report on the synthesis, new crystal structures, polymorphism, and luminescence utilizing the antenna effect for these complexes.…”

“…Solvent inclusion has been encountered for acetone, ethanol, CHCl 3 , and CH 2 Cl 2 ( Ln = Y, La, Ce, Nd, Sm, Eu, and Tb) , . Numerous solvent‐free Ln (NO 3 ) 3 (Ph 3 PO) 3 complexes have also been structurally characterized for Ln = Y, La, Pr, Nd, Sm, Gd, and Eu , , , . Polymorphism is clearly an important factor in these series of complexes, given the fact that two polymorphs each have been identified for Nd(NO 3 ) 3 (Ph 3 PO) 3 ,, and Gd(NO 3 ) 3 (Ph 3 PO) 3 .…”
