Mononuclear and icosanuclear spin-crossover complexes, [Fe] [Fe 20 ], were synthesized. has a bis-chelate structure, while ] ring-shape structure comprising four [2 × 2] grid moieties mononuclear units.

Glutathione,ascorbicacidand many commonly used antibiotics falsely elevate uric acid concentrations when measured with the Du Pont “aca,” in which the copper-chelate method is used. L-Dopa interferes with both the copper-chelate method and the Technicon “SMA 12/60” phosphotungstate method. A new kinetic uricase method has been developed for use on the Du Pont aca. This kinetic uricase method ha...

Exposure of the uranium(IV) complex, Cp(P)U((Mes)PDI(Me)) (1) ((Mes)PDI(Me) = 2,6-((Mes)N=CMe)2–C5H3N; Mes = 2,4,6-trimethylphenyl; Cp(P) = 1-(7,7-dimethylbenzyl)cyclopentadienyl), which contains a [(Mes)PDI(Me)](3−) chelate, to I2, Cl2, PhSeCl, and PhEEPh (E = S, Se, Te) results in oxidative addition to form the uranium(IV) family, Cp(P)U(XX′)((Mes)PDI(Me)) (X = X′ = I, Cl, EPh; X = SePh, X′ =...

The positron emitting isotope (89)Zr is an ideal radionuclide for use in positron emission tomography (PET) imaging with monoclonal antibodies (mAbs). This article reviews the cyclotron physics of (89)Zr production, and the chemical separation methods for isolating it from yttrium target material. (89)Zr coordination with the bifunctional chelate desferrioxamine B is discussed, along with the c...
