Crystal structure and Hirshfeld surface analysis of a pyridiniminium bromide salt: 1-[2-(adamantan-1-yl)-2-oxoethyl]pyridin-4-iminium bromide

2018

The asymmetric unit of the title pyridiniminium halide salt comprise of one cation and one anion. In the crystal, mol­ecules are linked by N—H⋯Br and C—H⋯O hydrogen bonds, C—H⋯π inter­actions, and π–π inter­actions into layers. The inter­molecular inter­actions in the crystal structure are qu­anti­fied by Hirshfeld surface analysis.

Crystal structure and Hirshfeld surface analysis of (2E)-3-(3-bromo-4-fluorophenyl)-1-(3,4-dimethoxyphenyl)prop-2-en-1-one

2018

The title compound is constructed from two aromatic rings (3-bromo-4-fluoro­phenyl and 3,4-di­meth­oxy­phen­yl), which are linked by a C=C—C(=O)—C enone bridge and form a dihedral angle of 17.91 (17)°. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds enclosing rings of (14) graph-set motif to form layers parallel to (10).
