Abstract:

The co-crystal of succinic acid with imidazolidin-2-one was mechanochemically prepared and its structure was studied by powder and single-crystal X-ray diffraction. This compound crystallizes in the triclinic system with space group P-1. The molecular structure and crystal packing are stabilized mainly by intermolecular O--H···O and N--H···O hydrogen bonds interactions, forming a supramolecular assembly with bi-dimensional hydrogen bond networks along the [110] diagonal joined by C44(22) chains and R22(8) amide-acid dimers which running along the ba plane. These hydrogen bonds contribute to the stabilization of the crystal structure that packs with an efficiency of 69.1 % in a planar sheet structure similarly to the even diacid co-crystals containing imidazolidin-2-one. Hirshfeld surface analysis was used for visually analyzing intermolecular interactions in the crystal structure.
