The binuclear ytterbium complex Ph2Yb(THF)(μ-Ph)3Yb(THF)3 (1) was obtained in reactions of naphthaleneytterbium C10H8Yb(THF)2 with diphenylmercury or triphenylbismuth in THF.An X-ray crystallographic study (a = 11.099(2), b = 19.876(4), c = 19.723(4) Angstroem, β = 103.33(3) deg, Z = 2, space group P21) showed that the molecule of 1 has two Yb atoms coupled by three bridging Ph groups, which are linked with the first Yb atom by an η1 bond and with the second one by an unsymmetrical η2 bond.In addition the first Yb atom has an η1 bond with two terminal Ph groups and one coordinated THF molecule whereas the second Yb atom is linked with three THF molecules.The coordination of both Yb atoms is a distorted octahedron.In the crystal, there are two symmetrically independent molecules of 1 with a similar structure.The Yb-C (terminal Ph) bond length is 2.388-2.463 Angstroem.The η1- and η2-Yb-C (bridging Ph) bond distance varies in the ranges 2.475-2.584, 2.547-2.751 and 2.877-3.250 Angstroem.The magnetic moment μeff(per YbIII atom) is 4.0 +/- 0.05 μB.Reactions of 1 with water, HCl, Br2, MeI and CO2 give benzene, bromobenzene, toluene and PhCOOH, respectively.

The preparation of organolanthanoid species from diorganomagnesium and lanthanoid salt is discussed. Treatment of cerium trichloride or ytterbium trichloride with diorganomagnesium gave the corresponding organolanthanoid species much more efficiently than treatment of the salt with organomagnesium halide.
Water-soluble Yb3+, Tm3+ codoped NaYF4 nanoparticles: Synthesis, characteristics and bioimaging

, p. 70 - 73 (2012)
Water soluble NaYF4 nanocrystals codoped with 20 mol% Yb 3+, 0.5 mol% Tm3+ were prepared by a facile solvothermal approach using polyvinylpyrrolidone (PVP) as a surfactant. The upconversion NaYF4 nanocrystals were pure cubic phase with an average size of ~40 nm. They could be well redispersed in water to form a clearly transparent solution without obvious precipitation. With the excitation of a 980-nm diode laser, the nanocrystal solution presents bright violet and blue upconversion luminescence. These upconversion nanoparticles (UCNPs) were incubated with HeLa cells at 37 °C for 24 h, and bright blue upconversion luminescence were observed from the UCNPs endocytosed into the HeLa cells on a microscope equipped with a 980-nm fiber laser. These results indicated that the UCNPs had potential applications for biological imaging as luminescent probes.
