1,4-Bis(3-methyl­phen­yl)piperazine-2,5-dione

The asymmetric unit of the title compound, C(18)H(18)N(2)O(2), consists of two independent mol­ecules, each of which is located about a center of inversion. The mol­ecules are not planar, showing dihedral angles of 55.84 (9) and 54.10 (8)° between the piperazinedione and the aromatic rings. The pipe...

description The asymmetric unit of the title compound, C(18)H(18)N(2)O(2), consists of two independent mol­ecules, each of which is located about a center of inversion. The mol­ecules are not planar, showing dihedral angles of 55.84 (9) and 54.10 (8)° between the piperazinedione and the aromatic rings. The piperazine N atoms exhibit a planar configuration. The crystal packing is stabilized by inter­molecular C—H⋯O hydrogen bonds.
