Аннотация: Two new complexes [Cu(Phen)2(H2O)](Hba)2∙3H2O (1) and [Ni(Phen)3](Htba)2]∙Phen∙2H2O (2) (Phen = 1,10-phenanthroline, Hba− = barbiturate ion, Htba− = thiobarbiturate ion) have been synthesized and characterized by elemental analysis, single-crystal and powder XRD, magnetic measurements, TG-DSC, FT-IR, and Vis absorption spectra. Complex 1 shows a distorted square pyramidal geometry around the copper (II) metal center. The coordination around the Ni atom is a distorted octahedron NiN6. The 3D and 2D supramolecular structures of 1 and 2 are formed respectively by intermolecular H-bonds. Two N–H⋯O hydrogen bonds in 1, and N–H⋯O, N–H⋯S hydrogen bonds in 2 form infinite chains. As a result of π–π interactions, similar 4-membered zigzag chains in structures 1 and 2 respectively are formed. © 2020 Elsevier B.V.
