Abstract

The complexes [Ln(Ph₂pz)₃(DME)₂] and [Ln(ffiu₂pz)₃(DME)] (Ln = La, Nd, Er; Ph2pzH = 3,5-diphenylpyrazole; ffiu₂pzH = 3,5-di-terf-biitylpyrazole; DME = 1,2-dimethoxyethane) have been prepared by reaction of the lanthanoid metal with bis(pentafluorophenyl)mercury and the pyrazole in DiME. The molecular structures of [Er(Ph₂pz)₃(DME)2] (3) and [Nd{fl3u2pz}3(DME)]oc (5) have been determined by X-ray diffraction. Complex 3 has nine-coordinate Er with three chelating Ph₂pz ligands and one chelating and one η¹-bound DME. There is a trigonal prismatic arrangement of the oxygen donors and the centres of the N-N bonds. 5 was found to be a linear polymer with transoid DME ligands bridging Nd(tBu₂pz)₃ units in a novel manner. The centres of the N-N bonds (which are essentially coplanar with Nd), and the oxygen donor atoms adopt an arrangement intermediate between trigonal-bipyramidal and square-pyramidal [O-Nd-O 153.5(2)°].
