Herein, a new Ni(II) carboxylate polymer, [Ni(Pyr)·4H2O]Phth, is synthesized by the reaction of NiSO4·7H2O with equimolar amounts of phthalic acid (PhthH2) as the counter-anion and pyrazine (Pyr) as an ancillary ligand in aqueous media. The crystal structure of [Ni(Pyr)·4H2O]Phth is investigated by single
crystal X-rays diffraction analysis, which inferred the ionic nature of the
complex. In cation, the Ni-center is coordinated by two pyrazine rings and four water molecules to form an octahedral coordination geometry. The
crystal structure exists as a one-dimensional polymeric structure. The crystal
packing is stabilized by O—H⋯O and C—H⋯O bonding. The
non-covalent interactions are investigated by Hirshfeld surface analysis. The
enrichment ratio delivers the tendency of the interaction of the pair of
chemical moieties, which are involved in the packing of crystals. Moreover, void
analysis is executed to look at the packing efficiency, which helps in
predicting the mechanical response of the compound.
Keywords: phthalic acid, single crystal X-ray diffraction, supramolecular assembly, Hirshfeld surface analysis, non-covalent interactions
