Crystal structure of 1,1′-[selanediyl­bis(4,1-phenyl­ene)]bis­(2-chloro­ethan-1-one)

In the title mol­ecule, C(16)H(12)Cl(2)O(2)Se, 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—C(ar)—C(ar); ar = aromatic) facing the Se atom are 120.0 (3) and 119.4 (3)°. The Se atom is essentiall...

Descripción
Sumario:In the title mol­ecule, C(16)H(12)Cl(2)O(2)Se, 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—C(ar)—C(ar); 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—C(ar)—C(ar)—C(ar) torsion angles of −179.2 (3) and −179.7 (3)°. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds forming chains propagating along the a-axis direction. The chains are linked via C—H⋯π inter­actions, forming a three-dimensional network.
