The development of a novel experimental capability of nuclear resonant inelastic X-ray scattering at high pressure and low temperature is presented. The new capability is demonstrated by studying the Fe-specific phonon density of states and magnetism in Eu57Fe2As2.

The title B12 model compound, {2,2′-[1,2-ethanediylbis(nitrilomethylidyne)]diphenolato-N,N′,O,O′}(isobutyl)cobalt(III), [Co(C4H9)(C16H14N2O2)(H2O)], has distorted octahedral stereochemistry around the CoIII ion. The equatorial salen ligand displays a `stepped' conformation, which is the prefered conformation in penta- and hexacoordinate organocobalt-salen complexes. The axial Co—C bond length is close to that of coenzyme B12 and in accordance with that of other B12 models, but the difference in the axial Co—O bond length as well as the deviation from the ideal tetrahedral value of the Co—C—C angle are due to the trans influence of the axial isobutyl group, which has stronger σ-donor power.

The optical design of a soft X-ray spectrometer that utilizes Wolter mirrors to enable imaging-mode spectroscopy with a beam-size independent spatial resolution in, for example, tandem catalysts in reaction is presented. When such a spectrometer is used in pump–probe experiments to study the transient electron dynamics, the imaging capability of the Wolter mirrors can offer femtosecond time delay between the pump and probe beams with non-collinear wavefronts.

In the title compound, C12H28N+·Br−·H2O, the ionic pairs formed by n-dodecylammonium cations and bromide anions are arranged into thick layers; these layers are linked in a nearly perpendicular fashion [the angle between the layers is 85.84 (5)°] by hydrogen-bonding interactions involving the water molecules. The methylene part of the alkyl chain in the cation adopts an all-trans conformation. In the crystal structure, molecules are linked by intermolecular N—H

A crystal structure of zebrafish Plk1 reveals the binding of an extended ATP-competitive inhibitor that targets the adaptive pocket and helps to order the activation segment of the kinase. The conformation of the segment resembles that observed in a nonphosphorylated ligand-free wild-type kinase domain.

In the title salt, C21H21Cl2N2O2+·NO3−, the imidazole ring makes dihedral angles of 43.39 (14) and 10.9 (2)° with the 4-methylphenyl and 2,4-dichlorophenyl rings, respectively. The molecule adopts a Z conformation about the C=C double bond, which links the imidazole ring to the 4-methylphenoxy unit via an ethoxy chain. In the crystal, cations and anions are linked into chains by N—HO and C—HO hydrogen bonds.

In the molecule of the title compound, C13H12O, the two aromatic rings are oriented at a dihedral angle of 2.90 (3)°. An intramolecular C—HO hydrogen bond results in the formation of a non-planar six-membered ring, which adopts an envelope conformation. In the crystal structure, intermolecular C—HO hydrogen bonds link the molecules.

The substrate-free E. coli tyrosine amintotransferase (eTAT) bound with a cofactor pyridoxal 5′-phosphate (PLP) was crystallized in trigonal space group P32. The low-resolution crystal structure shows that the substrate-free eTAT has a tertiary structure similar to the open form of aspartate aminotransferase.
