Erbium produces a brilliant emerald-green thermoluminescence, as discussed in the previous Chapter. Like the mixed oxides containing holmium compared with H02O3, there is more fine-structure in the emission spectrum of Er20s than of the mixed oxides of erbium(III). A common feature is the sharp edge of...

A ternary compound of erbium with copper and antimony of the 3 3 4 stoichiometric ratio was identified and studied by means of an X-ray analysis by Skolozdra et al. (1993). The Er3Cu3Sb4 compound was found to have the Y3Au3Sb4 type structure with a lattice parameter of a = 0.9458 (X-ray powder diffraction). For experimental details, see the Y-Cu-Sb system. 

R CN (Table 2) [86]. The molecular structure of the 2,2-dimethylpropanonitrile derivative contains unsymmetrically bridging alkylidene amide ligands. Reaction of the yttrium and erbium hydride species with isonitrile results in the formation of a formidoyl moiety (Table 2) [87], Surprisingly the Ln-N interaction is in the range of the nitrile product A similar molecular structure was found in the oximato complex [Cp2Gd(/i-t/2-ONCMe2)]2 (Gd-Nav 2.42(1) A) [88]. 

The isostructural solutions formed by yttrium(III) and erbium(III) have been used to study the structures of their halide complexes in aqueous solutions at different concentrations (35). The RDFs for some erbium(III) bromide and chloride solutions with different metal ion concentration and halide to metal ratios are given in Fig. 20 after elimination of the nonmetal interactions. For comparison those of three perchlorate solutions of similar concentrations are also given. For all of these solutions the peaks at 2.35 A, which correspond to the inner coordination sphere of the metal ion, are nearly the same and are closely reproduced by a theoretical peak calculated for 8.0 Er-H20 interactions. This indicates that the anions do not penetrate the first...

More precise structural information can be obtained when a separation of interactions can be made. The RDFs for 2.9 M solutions of erbium(III) and yttrium(III) nitrate, which are isostructural (36), are...
