[SmO(cbz)(thf)]·2CH: A Polynuclear Samarium Oxo Cluster Obtained from Carbazole-Driven Oxidation of Samarium Nanoparticles.

Zerovalent samarium nanoparticles (1.7 ± 0.2 nm in size) are used as the starting material to prepare single crystals of the novel polynuclear samarium oxo cluster [SmO(cbz)(thf)]·2CH.

Liquid-Phase Synthesis of Highly Reactive Rare-Earth Metal Nanoparticles.

The first liquid-phase synthesis of high-quality, small-sized rare-earth metal nanoparticles (1-3 nm)-ranging from lanthanum as one of the largest (187 pm) to scandium as the smallest (161 pm) rare-earth metal-is shown. Size, oxidation state, and reactivity of the nanoparticles are examined (e.g.

18-Crown-6 Coordinated Metal Halides with Bright Luminescence and Nonlinear Optical Effects.

The crown-ether coordination compounds Zn(18-crown-6), Eu(18-crown-6) (: Cl, Br, I), MnI(18-crown-6), MnCl(18-crown-6), MnI(18-crown-6), and MnI(18-crown-6) are obtained by ionic-liquid-based synthesis. Whereas (18-crown-6) (: Zn, Eu) show conventional structural motives, MnCl(18-crown-6), MnI(18-crown-6), and MnI(18-crown-6) exhibit unusual single Mn tetrahedra coordinated to the crown-ether complex. Surprisingly, some compounds show outstanding photoluminescence.
