Once again, crystal structure data are necessary in order to show how the lanthanides bind in proteins. With the help of D. C. Philhps group (Oxford), we have made a start with lysozyme showing that Gd binds between the two carboxylate groups—t.e., exactly at the active site. We 42) have done NMR studies on several diflFerent cations of the lanthanide series to discover which is most useful. Gadolinium (broadening-probe), europium, and holmium (shift-probes) have much...

Although the crystal structures of about half of the rare earth metals were well established by the mid- to late 1930 s the work by Klemm and Bommer (1937) stands as a landmark paper because they determined the crystal structures and the lattice parameters of all the lanthanides, except holmium, samarium and radioactive promethium. In so doing they... 

It can only be concluded, from the impact data tabulated in table 8.7, that all the rare earth metals have low fracture toughness in the as-cast condition. Although neodymium, holmium, and ytterbium have somewhat better impact properties than the other rare earth metals this is not explained by purity or crystal structure. Furthermore, the three metals (yttrium, dysprosium and erbium) tested at 477 K did not exhibit a strong tendency towards improved impact properties with increased test temperature.

The second type of RNaSi04 compound exists for lanthanides from neodymium to holmium. The structure is tetragonal, with space group I4/m or 14. Structure refinement has been carried out for the Sm compound from film data and for the Gd compound from single crystal data (Chichagov et al., 1967 Fallon and Gatehouse,... 

T-Ray data indicate that BiPsOi4 is an isotype of the ultraphosphate LaP50j4, and there are strong structural relations with the holmium compound. The latter can be obtained in both orthorhombic Pnmd) and monoclinic (C2Jc) forms, and the ultraphosphate structure for both is shown by single-crystal measurements. ... 

Holmium forms orthorhombic crystals of composition NaHo4(Ge04)020H in hydrothermal conditions. The structure contains 7-coordinated rare earth atoms forming a polyhedral band. The germanate groups are linked to the holmium and sodium coordination polyhedra (Christensen, 1972).
