Аннотация: Co-crystallization of 1,3-diethyl-2-thiobarbituric acid (HDetba) with 2,2′-bipyridine (Bipy) and 1,10-phenanthroline (Phen) results in preparing a salt co-crystal, BipyH(Detba)(HDetba) (1), and the salt, PhenH(Detba)·H2O (2). The compounds are characterized by single–crystal and powder X–ray diffraction and TG-DSC. The nitrogen atoПоказать полностьюms of BipyH+ adopt a cis conformation and the N–C–C–N torsion angle is −17.3(1)º. There are six intermolecular hydrogen bonds O–H⋯O, N–H⋯O, C–H⋯O and C–H⋯S in (1) which form a 2D plane network. One Detba– ion and one HDetba molecule form a pair by means of O–H⋯O hydrogen bonds. Detba− anions in (2) do not form dimers, they are connected by N–H⋯O, C–H⋯S, and C–H⋯O hydrogen bonds only with PhenH+ cations and water molecules which form a 3D net. Different π−π interactions between the rings are found in (1)−(2). © 2018 Elsevier B.V.
