The structure was solved by standard heavy-atom techniques. Least-squares refinement has led to a final value of the conventional R index of 0.105 based on 1766 reflections. The titanium atom is coordinated to the four nitrogen atoms and to the oxygen atom. The methoxo ligand is significantly...
The molecular structure of methyl-2-nitrophenyl sulphide has been determined in the gas phase by electron diffraction. The following values were obtained for bond lengths (rg/Å): S—C(aryl), 1.774 ± 0.006; S—C(methyl), 1.809 ± 0.006; N—C, 1.468 ± 0.006; (CC)mean, 1.400 ± 0....
First of all, amyloids can be formed from proteins with very different amino acid sequences; the common denominator is that the individual proteins constituting the amyloid fold predominantly into a β-sheet structure. Secondly, the formation of the fibril occurs through non-covalent interactions ...
The molecule is monomeric and has a trigonal prismatic structure. The molecular parameters are as follows: ra(Y-O)=2.230(5) Aring, ra(C-O)=1.283(4) Aring, ra(C-C ring)=1.411(8) Aring, ra(C-C tert)=1.503(13) Aring, ra(C-C meth)=1.553(6) Aring, angOYO=75.0(11)deg, ...

coordination of a Mg2+ion and formation of a substructure for binding thepABA molecule21. The conformation of the loop 1-loop 2 substructure enabling the binding ofpABA requires the presence of pyrophosphate, which was visualized in the crystal structure of the near-transition state complex ofYpD...
The structure was determined using observed data and refined to an R of 0.0376. The molecule has (Ci) symmetry with a planar, central Re2C2 ring. The carbyne ligands bridge symmetrically with the Re–C multiple bond component delocalised. The Re–Re distance of 2.557 Å is rather long, ...
The crystal and molecular structure of the title compound have been determined by single-crystal X-ray analysis All non-hydrogen atoms conform to space group P2/c with a= 6·536 ± 0·007, b= 7·768 ± 0·008, c= 17·194 ± 0·017 Å, β= 108·8 ± 0·1°. Z= 2. The ...
The crystal structure of the cytotoxic endonuclease domain from the bacterial toxin colicin E9 in complex with its cognate immunity protein Im9 reveals that the inhibitor does not bind at the active site, the core of which comprises the HNH motif found i
