In the title compound, [AgCl(C7H7N3O2S)(C18H15P)2], the AgI ion is in a distorted tetra-hedral coordination environment formed by P atoms from two tri-phenyl-phosphane ligands, one terminal S atom from the 1-(4-nitro-phen-yl)thio-urea ligand and a chloride ion. In the crystal, bifurcated (N-H)2⋯Cl hydrogen bonds [with graph-set motif R21(6)] connect complex mol-ecules, forming zigzag chains alo...

An analysis of hydrogen bonds involving ester Osp3 atoms as acceptors has been performed based on the data extracted from the Cambridge Structural Database [Allen (2002). Acta Cryst. B58, 380-388; version 5.25, November 2003], using the ConQuest package to evaluate the stereochemical and electronic properties of the acceptors. Evidence for the existence of this particular type of hydrogen bond ...

In the title compound, C(17)H(18)ClN(3)O(3), the dihedral angle between the planes of the two benzene rings is 1.03 (7)°. The overall conformation of the mol-ecule is influenced, in part, by electron delocalization and by an intra-molecular bifurcated O-H⋯(O,N) hydrogen bonds. The O atoms of the nitro group, one of which serves as an H bond acceptor, are disordered over two sets of sites with r...

The crystal of the title compound, C(13)H(12)N(2)O(6), contains a bifurcated intra-molecular hydrogen bond between the N-H group and one of the O atoms from both the nitro group and the dioxane-4,6-dione moiety. In addition, mol-ecules are linked by a series of inter-molecular C-H⋯O secondary inter-actions. The dihedral angles between the benzene ring and the nitro group and the conjugated part...

In the title solvate, C15H15N3O2S·CH3OH, the thio-semicarbazone mol-ecule is approximately planar; the maximum deviation from the mean plane is 0.4659 (14) Å and the dihedral angle between the aromatic rings is 9.83 (8)°. This conformation is supported by an intra-molecular N-H⋯N hydrogen bond. In the crystal, the thio-semicarbazone mol-ecules are linked into dimers by pairs of N-H⋯S hydrogen b...

Molecular dynamics (MD) simulations combined with water-water H-bond angle analysis and calculation of solvent accessible surface area and approximate free energy of solvation were used to determine the influence of hydroxyl orientation on solute hydration and surrounding water structure for a group of chemically identical solutes-the aldohexopyranose sugars. Intramolecular hydrogen bond cooper...

A series of sixteen Schiff bases (derivatives of salicylaldehydes and aryl amines) was studied to reveal the influence of substituents and the length of the linker on the properties of the H-bonding formed. In theory, two groups of compounds, derivatives of 2-(2-hydroxybenzylidenoamine)phenol) and 2-hydroxy-N-(2-hydroxybenzylideno)benzylamine, can form different types of H-bonds using one or tw...

A diketiminato zinc amide complex, LZnNMe2 (1) [L = CH{(CMe)2(2,6-(i)Pr2C6H3N)2}], was prepared and investigated for the catalytic hydroamination of 2,2-dimethylpent-4-en-1-amine. The reaction with the amino olefin resulted in a transamination reaction and the subsequent insertion of the olefin moiety into the metal-amide bond. However, the reaction stopped at this point providing access to the...

An unprecedented method that makes use of the cooperative interplay between molecular iodine and photoredox catalysis has been developed for dual light-activated intramolecular benzylic C-H amination. Iodine serves as the catalyst for the formation of a new C-N bond by activating a remote Csp3 -H bond (1,5-HAT process) under visible-light irradiation while the organic photoredox catalyst TPT ef...
