The first molecular complexes of holmium and erbium in the +2 oxidation state have been generated by reducing Cp'(3)Ln [Cp' = C(5)H(4)SiMe(3); Ln = Ho (1), Er (2)] with KC(8) in the presence of 18-crown-6 in Et(2)O at -35 °C under argon. Purificatio

Liquid fluoride thorium reactors have been considered as replacements for uranium-based nuclear reactors, having many economic and environmental advantages. The production of thorium is usually accompanied by the separation of thorium from rare earth

The finding of new metal alloyed nanocrystals (NCs) with high catalytic activity and low cost to replace PtRu NCs is a critical step toward the commercialization of fuel cells. In this work, a simple cation replacement reaction was utilized to synthe

An entirely new type of chalcogenide cluster and a new structural mechanism for the formation of large semiconducting tetrahedral clusters have been revealed as a result of crystallization of a templated indium sulfide consisting of an unprecedented

We found that metal-organic framework (MOF) compounds M(2)(dhtp) (open metal M = Mg, Mn, Co, Ni, Zn; dhtp = 2,5-dihydroxyterephthalate) possess exceptionally large densities of open metal sites. By adsorbing one CH(4) molecule per open metal, these s

Supertetrahedral Tn clusters are exact fragments of a cubic ZnS type lattice. Thus far, Tn clusters up to T4 with 20 metal sites can be synthesized in a discrete molecular form. Yet, synthesis of larger discrete supertetrahedral clusters still remain

One-to-one complexes between Li, Na, K, and Cs atoms and NH/sub 3/ have been studied by using matrix IR spectroscopy. New bands at 1133, 1079, 1064, and 1049 cm/sup -1/ are assigned to perturbed nu/sub 2/ modes, and bands at 3277, 3294, 3292, and 328

A turbulent flow apparatus was used for qualitative study of the exchange of N/sup 15/H/sub 3/ between solvent and ligands in complex metal ammines. The N/sup 15/-enriched liquid NH/sub 3/ was mixed in approximately O.O1 sec with an unenriched soluti
