Exchange interactions and XPS O1s spectra in polynuclear lanthanide complexes with dibenzoylmethanide and 4-hydroxy-2,1,3-benzothiadiazole

Abstract Magnetic properties of tetra- and pentanuclear complexes, Ln 4 (dbm) 4 (O-btd) 6 (OH) 2 , Ln 4 (dbm) 6 (O-btd) 4 (OH) 2 and Ln 5 (dbm) 10 (OH) 5 (Ln = Er, Dy, Yb; dbm = dibenzoylmethanide, O-btd = 4-hydroxy-2,1,3-benzothiadiazole) were studied. The X-ray photoelectron spectroscopy (XPS) O1s spectra of the studied compounds were obtained and analyzed. The mechanisms of exchange interactions in these compounds are discussed.
