    • Abstract

       

      Reaction of 𝑁-(phenyl)-2-pyridinecarboxamide (HL1) and 𝑁-(𝑝-tolyl)-2-pyridinecarboxamide (HL2) ligands with MnCl2.4H2O affords complexes [(HL1)2MnCl2] 1 and [(HL2)2MnCl2] 2. The structures of 1 and 2 were determined by three-dimensional X-ray crystallography revealing that the MnII ions assume distorted octahedral geometry with coordination by two HL1/HL2 ligands providing two pyridine N and two amide O and two chloride ions. Notably, secondary interactions [C-H$\cdots$Cl (pyridine 3-H hydrogen) and N-H$\cdots$Cl (amide NH hydrogen)] triggered by MnII-coordinated chloride ions acting as hydrogen bonding acceptors generate self-complementary dimeric tectons, which lead to 2D supramolecular architectures.
