Bis(4-acetyl­phen­yl) selenide

In the title compound, C16H14O2Se, the dihedral angle between the benzene rings is 87.08 (11)°. In the crystal, mol­ecules are linked into layers parallel to the bc plane by inter­molecular C—H⋯O hydrogen bonds

Crystal structure of 1,1'-[selanediyl-bis(4,1-phenyl-ene)]bis-(2-chloro-ethan-1-one)

International audienceIn the title mol-ecule, C16H12Cl2O2Se, the C-Se-C angle is 100.05 (14)°, with the dihedral angle between the planes of the benzene rings being 69.92 (17)°. The average endocyclic angles (Se-Car-Car; ar = aromatic) facing the Se atom are 120.0 (3) and 119.4 (3)°. The Se atom is essentially coplanar with the benzene rings, with Se-Car-Car-Car torsion angles of -179.2 (3) and -179.7 (3)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds forming chains propagating along the a-axis direction. The chains are linked via C-H⋯π inter-actions, forming a three-dimensional networ

3,5-Dibromo-4-methylpyridine

The title compound, C6H5Br2N, lies on a mirror plane. In the crystal, molecules are linked by Br...N and Br...Br interactions, forming zigzag chains along [010]. The chains are linked by offset π–π interactions [intercentroid distance = 3.5451 (3) Å], forming a three-dimensional framework
