Synthesis and Crystal Structure of 1,4-Di(1-naphthyl)-2,5-piperazinedione

Abstract

The crystal structure of 1,4-di(1-naphthyl)-2,5-piperazinedione has been determined by single crystal X-ray diffraction method. The crystal belongs to monoclinic system, space group C2/c with unit cell constants a=28.71 (2), b=5.721 (4), c=11.451 (9) Å, V=1847 (2) ų, Z=8, Dc=1.368 g/cm³ μ=0.092mm^–1, F(000) = 792, R and wR are 0.0871 and 0.2836, respectively for 1601 unique reflections with 998 observed reflections (I > 2σ(I)). The molecules are interconnected into three-dimensional network by O1W-H1W1^…O1 & C8-H8^…O1W  intermolecular interactions.
