1,2-Diphenyl-2-[4-(4-pyridyl)benzyl-idene-hydrazono]ethan-1-one.

ABSTRACT: In the title compound, C(26)H(19)N(3)O, the dimethyl-ene hydrazine (-C=N-N=C-) unit is approximately planar, the torsion angle around the N-N bond being 162.2?(6)°. The phenyl and benzoyl-phenyl rings at one end of the hydrazine unit are aligned at angles of 9.5?(5) and 88.5?(4)°, respectively, with respect to the hydrazine unit, whereas the benzene ring at the other end is twisted by an angle of 14.4?(4)°. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by inter-molecular C-H?O hydrogen bonds. The monoclinic crystal under investigation shows pseudo-merohedral twinning with twin fractions of 0.63 and 0.37.

Project description:In the title compound, {[Ag(C(30)H(20)N(6))][SbF(6)]}(n), the Ag(+) cation has a three-coordinate environment completed by three N atoms of the 1,2-bis-[(3-cyano-benzyl-idene)hydrazono]-1,2-diphenyl-ethane ligand. The Ag(+) cation coordination geometry is best described as distorted T-shaped. The crystal structure forms a three-dimensional structural polymer.

Project description:In the title complex, {[Ag(2)(CF(3)O(3)S)(2)(C(30)H(20)N(6))]·C(6)H(6)}(n), the two independent Ag(I) ions are each coordinated by two N atoms and one O atom in a 'T-shaped' geometry.

The crystal structure is stabilized by weak inter-molecular C-H?O hydrogen bonds.

Chlorido{N-[(E)-2-(diphenyl-phosphan-yl)benzyl-idene]-2-(thio-phen-2-yl)ethan-amine-?P}gold(I).

Project description:The title compound, [AuCl(C(25)H(22)NPS)], crystallizes with two independent mol-ecules in the asymmetric unit in which the thio-phene fragments are disordered over two sets of sites with 0.537?(10):0.463?(10) and 0.701?(9):0.299?(9) occupancy ratios. In both cases, the thio-phene ring is rotated by approximately 180° for the second component. Important geometrical parameters include Au-P = 2.235?(2) and 2.237?(2)?Å, Au-Cl = 2.286?(2) and 2.292?(2)?Å, and P-Au-Cl = 177.39?(8) and 172.63?(7)°. Weak inter-molecular C-H?Cl inter-actions are observed in the crystal structure.

Crystal structure and mol-ecular docking study of (<i>E</i>)-2-{[(<i>E</i>)-2-hy-droxy-5-methyl-benzyl-idene]hydrazinyl-idene}-1,2-di-phenyl-ethan-1-one.

Project description:The title compound, C22H18N2O2, is a Schiff base that exists in the phenol-imine tautomeric form and adopts an E configuration with respect to the C=N bond. The mol-ecular structure is stabilized by an O-H⋯N hydrogen bond, forming an S(6) ring motif. In the crystal, pairs of C-H⋯O hydrogen bonds link the mol-ecules to form inversion dimers. Weak π-π stacking inter-actions along the a-axis direction provide additional stabilization of the crystal structure. The mol-ecule is non-planar, the aromatic ring of the benzaldehyde residue being nearly perpendicular to the phenyl and 4-methyl-phenol rings with dihedral angles of 88.78 (13) and 82.26 (14)°, respectively. A mol-ecular docking study between the title mol-ecule and the COVID-19 main protease (PDB ID: 6LU7) was performed, showing that it is a potential agent because of its affinity and ability to adhere to the active sites of the protein.

Project description:The asymmetric unit of the title compound, C(19)H(15)N(3)O(2), contains two mol-ecules, both of which show an E conformation of the imine bond.

In the crystal, C-H?? inter-actions and C-H?O hydrogen bonds are observed growing along the a, b and c axes, resulting in a complex supramolecular array.
