Conformational dimorphism of 2,2′-methylenebis(isoindoline-1,3-dione)

Acta Crystallographica Section E: Crystallographic Communications, 2019
In this study, a new monoclinic polymorph (space group C2/c) of 2,2′-methylenebis(isoindoline-1,3-dione), C17H10N2O4, is reported and compared to the previously reported triclinic polymorph (space group P\overline{1}).

Crystal structure of a second monoclinic polymorph of 3-methoxybenzoic acid with Z′ = 1

Acta Crystallographica Section E: Crystallographic Communications, 2019
A new polymorphic form of the title compound, C8H8O3, is described in the centrosymmetric monoclinic space group P21/c with Z′ = 1 as compared to the first polymorph, which crystallizes with two conformers (Z′ = 2) in the asymmetric unit in the same ...

Spotlight on Alkali Metals: The Structural Chemistry of Alkali Metal Thallides

Crystals, 2020
Alkali metal thallides go back to the investigative works of Eduard Zintl about base metals in negative oxidation states. In 1932, he described the crystal structure of NaTl as the first representative for this class of compounds.

Structure of human transthyretin complexed with bromophenols: a new mode of binding [PDF]

, 2000
The binding of two organohalogen substances, pentabromophenol (PBP) and 2,4,6-tribromophenol (TBP), to human transthyretin (TTR), a thyroid hormone transport protein, has been studied by in vitro competitive binding assays and by X-ray crystallography ...

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
