Crystal structure of (E)-N¹-[(anthracen-9-yl)methyl-idene]-N⁴-phenyl-benzene-1,4-di-amine.

ABSTRACT: The title compound, C₂₇H₂₀N₂, a Schiff base synthesized via a condensation reaction between anthracene-9-carbaldehyde and N-phenyl-p-phenyl-enedi-amine, crystallizes with three independent mol-ecules in the asymmetric unit. The three mol-ecules have slightly varying overall conformations, all having trans conformations with respect to the C=N bond. In the crystal, the packing features N-H?N hydrogen bonds, which connect mol-ecules into chains extending along the c-axis direction, inter-linked by C-H?? inter-actions (minimum H?Cg = 2.65?Å) into sheets lying parallel to (001).

Project description:The whole mol-ecule of the title complex, [Hg2Cl4(C18H15N3)2], is generated by inversion symmetry. It was synthesized from the pyridine-derived Schiff base N-phenyl-N'-[(pyridin-2-yl)methyl-idene]benzene-1,4-di-amine (PPMBD). The five-coordinated Hg(2+) ions have a distorted square-pyramidal environment defined by two N atoms, viz. the imine and the other pyridyl [Hg-N = 2.467 (6) and 2.310 (6) Å, respectively] belonging to the bidentate imino-pyridine ligand, and three Cl atoms [Hg-Cl = 2.407 (2), 2.447 (2) and 3.031 (2) Å]. The longest Hg-Cl bond is bridging about the inversion centre. In the ligand, the central ring and pyridine ring are oriented at a dihedral angle of 8.1 (4)°, while the planes of the pyridine ring and the terminal phenyl ring are oriented at a dihedral angle of 53.8 (4)°. In the crystal, mol-ecules are linked by N-H⋯Cl and C-H⋯Cl hydrogen bonds, forming sheets parallel to (001).

Crystal structure of 3,5-di-methyl-phenyl 2-nitro-benzene-sulfonate.

Project description:The title compound, C14H13NO5S, was synthesized via a nucleophilic substitution reaction between 3,5-di-methyl-phenol and 2-nitro-benzene-sulfonyl chloride.

An inter-molecular S=O⋯N inter-action between the sulfonyl and nitro groups, with an O⋯N distance of 2.9840 (18) Å, organizes the dimers into columns extending along [011]. These columns are further assembled into (111) layers through C-H⋯O inter-actions.
