Sažetak

The structure of 3(4-pyridil-methyl)amino-pyrrolidine-2,5-dione has been established by X-ray crystallography from diffractometer data with an F2 refinement to R = 0.0526 for 1999 observed reflections. The close packing of orthorhombic crystals space group Pbca (No. 61) with a = 11.595(4), b = 8.325(1), c = 20.452(4) Å, V = 1974.2(8) Å3, Z = 8, Dc = 1.381 Mg/m3, m = 0.824 mm–1 is built of herringbone-like molecular layers folded along the c axis and fused together by infinite chains of NH⋅⋅⋅O and NH⋅⋅⋅N hydrogen bonds perpendicular to one another. This prompted us to review and characterize the hydrogen bond networks formed by succinimides possessing an unsubstituted >NH group by the use of the Cambridge Structural Database (CSD), and our own earlier structure determinations. The common motifs of the hydrogen bond systems are analyzed using graph descriptions suggested by M. C. Etter. The influence of the hydrogen bonds on molecular close packing is also discussed.
