The first examples of mononuclear, structurally characterized triarylphosphine complexes of zirconium and hafnium are reported. The metathetical reactions of MCl4(THF)2 (M = Zr, Hf) with [iPrNP]Li(THF)2 ([iPrNP]- = N-(2-(diphenylphosphino)phenyl)-2,6-diisopropylanilide) or [MeNP]Li(THF)2 ([MeNP]- = N-(2-(diphenylphosphino)phenyl)-2,6-dimethylanilide) in toluene at -35 degrees C produced the cor...

X-ray crystal structures of two [(diphosphine)Au2 Cl2 ] complexes (in which diphosphine=P-Phos and xylyl-P-Phos; P-Phos=[2,2',6,6'-Tetramethoxy-4,4'-bis(diphenylphosphino)-3,3'-bipyridine]) were determined and compared to the reported structures of similar atropisomeric gold complexes. Correlations between the Au⋅⋅⋅Au distances and torsional angles for the biaryl series of ligands (MeOBIPHEP, S...

The cyclometalated acetate ruthenium complexes [Ru(C^N)(η2-OAc)(dppb)] (dppb = 1,4-bis(diphenylphosphino)butane; HC^N 2-phenylpyridine 1, benzo[h]quinoline 2, 1-phenylpyrazole 3, 2-phenyl-2-oxazoline 4) are easily obtained in 58-74% yield through a one-pot synthesis from...

In the two square-planar palladium(II) complexes chloro[(diphenylphosphinoamino)diphenylphosphine oxide]methylpalladium(II) dimethyl sulfoxide solvate, [Pd(CH3)Cl(C24H21NOP2)].C2H6OS, (I), and chloro{[2-(diphenylphosphino)phenyl]diethoxymethane}methylpalladium(II), [Pd(CH3)Cl(C23H25O2P)], (II), a trans disposition of the diphenylphosphino and chloro groups is observed. The Pd atom in both compl...

The stability of proteins under co-solvent conditions is dependant on the nature of the co-solvent; the co-solvent can alter a protein's properties and structural effects through bimolecular interactions between its functional groups and co-solvent particles. Ionic liquids (ILs) represent a rather diverse class of co-solvents that are combinations of different ions, which are liquids at or clos...
