Abstract
A series of heteroleptic lanthanide complexes [LnL3·Dipy] and [LnL3·Phen] (Ln = La – Nd, Sm – Yb, Dipy – α,α’-dipyridile, Phen – 1,10-phenantroline, HL (CAPh type ligand) = dimethyl-N-trichloracetylamido-phosphate, CCl3C(O)NHP(O)(OCH3)2) has been synthesized. The complexes have been characterized by means of the elemental analyse, X-ray diffraction, FT-IR and NMR spectroscopy. Crystal structure of [ErL3·Dipy] has been determined. Cell edge parameters: a = 11.9821(7) Å, b = 21.459(1) Å, c = 31.985(2) Å, β = 96.096(1)°, V =8177.8(8) Å3, Z=8, monoclinic, space group C2/c. Two CAPh ligands are coordinated via oxygen atoms of phosphoryl and carbonyl groups, forming six-membered cycles. The Ln- O(P) bonds are shorter than the Ln-O(C) bonds because of stronger affinity of the phosphoryl group for lanthanides. The Lippard-Russ and δ-criterions were used to characterize the erbium ion coordination polyhedron, it can be described as an distorted Hoard’s dodecahedron, mgg+m isomer.
