Abstract
A new series of lanthanide(III) nitrate complexes with 10-(2-dimethylamino-1-methyl) phenothiazine (isopromethazine) having the general formula Ln(IP)(2)(NO3)(2)]NO3, where Ln = La, Ce, Pr, Nd, Sm, Eu,Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and IP = isopromethazine have been prepared and characterized by elemental analysis, molar conductance, electronic, infrared, proton NMR spectra, magnetic moments and thermogravimetric studies. Isopromethazine acts as a bidentate ligand, coordinating through heterocyclic nitrogen and tertiary alkyl side chain nitrogen atoms. Two of the nitrate groups are coordinated in a bidentate fashion to the metal ion, while another nitrate ion remains uncoordinated. A coordination number of eight may be assigned to the metal ion in these complexes. The electronic spectra reveal the weak covalent character of the metal-ligand bond.
