Abstract

Single crystals of Ce(III) complex {[Ce₂(oPDA)₃(H₂O)₂]·2H₂O}_n (1) with O-donor ligand H₂oPDA (o-phenylenediacetic acid) were formed under solvothermal conditions. The crystal structure of 1 is one-dimensional and formed by chains of the Ce(III) ions linked via oPDA²⁻ dianions acting as pentadentate ligands with bridging and chelating functions. The Ce(III) central atom in 1 is nonacoordinated by eight oxygen atoms from four different oPDA²⁻ ligands and one oxygen atom of the aqua ligand yielding O₈O donor set. The investigation of the static susceptibility and magnetization suggested Δ/k_B = 317 K energy difference between the ground and the first excited doublet. Field induced slow magnetic relaxation was revealed in the investigation of alternating susceptibility. The alternation of the relaxation time with temperature confirmed the coexistence of quantum tunneling and Raman relaxation processes with anomalous coefficients for Raman relaxation.
