BINDING OF CATIONS TO 4F METAL-IONS - PREPARATION AND PROPERTIES OF LANTHANIDE(III) COMPLEXES CONTAINING THE PHENELZINIUM(1+) CATION AS A LIGAND

Treatment of Ln(2)(SO4)(3) . nH(2)O (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd; n = 8, 9) with phenelzine dihydrogen sulfate, (phzH(2))SO4, in 1 N H2S O4 yields polymeric complexes with the general formula [Ln(SO4)(2)(H2O )(2)(phzH)], which contain the phzH(+) cation as a ligand. The compoun ds have been characterized by elemental analyses, X-ray powder pattern s, thermal methods, magnetic susceptibilities and spectroscopic (IR, R aman, electronic diffuse reflectance and solid-state emission f-f spec tra) studies. The prepared complexes most probably consist of 7-coordi nated units, formed by four bridging bidentate sulfate groups, two ter minal aqua molecules and one cationic phzH(+) ligand.
