Kang, Quan-Peng published the artcileSymmetric containing-PMBP N2O2-donors nickel(II) complexes: Syntheses, structures, Hirshfeld analyses and fluorescent properties, Formula: C17H14N2O2, the publication is Polyhedron (2019), 38-50, database is CAplus.
One mononuclear Ni(II) complex [Ni(L1)(MeOH)2]·MeOH (1) and two novel trinuclear Ni(II) complexes [Ni3(L2)3(EtOH)6] (2) and [Ni3(L2)3(H2O)6] (3) constructed from sym. N2O2-donors chelating ligands (H2L1 and H2L2) were synthesized and characterized by elemental analyses, FT-IR, UV-Vis spectra and fluorescence spectra. The structures of all three complexes were confirmed by single crystal x-ray diffraction analyses. Complex 1 includes one Ni(II) atom, one completely deprotonated (L1)2- unit and two coordinated methanol mols., and forms an infinite 2D supramol. network via the intermol. hydrogen bonds. While complex 2 or 3 is trinuclear with three Ni(II) atoms, three completely deprotonated (L2)2- units and six coordinated ethanol or H2O mols. These self-assembling complexes form different dimensional supramol. structures through inter- and intramol. hydrogen bonds. Hirshfeld surface analyses for complexes 1, 2 and 3 were mapped with various functions and further quantification of intermol. interactions was made through the generation of 2D fingerprint plots. In addition, the fluorescence titration experiments were used to characterize fluorescence properties of complexes 1 and 2.
