AbstractA quinoline-containing semi-salamo-type ligand, HL, was synthesized and a dinuclear Ni(II) complex, [Ni2(L)2(NCS)2], produced. The complex experimentally analyzed by elemental analysis, fluorescence, UV–Vis spectroscopy. X-ray single crystal diffraction experiments showed that the is six-coordinate, structurally symmetric, phenoxy-bridged dimer with participation of SCN− in coordination to satisfy charge neutrality. self-assembly forms 2-D supramolecular network structure through hydrogen bonding π⋯π interactions. DFT calculations were performed on analyze its energy gaps, experiment verified TD-DFT calculation.

Coordination-Driven Salamo-Salen-Salamo-Type Multinuclear Transition Metal(II) Complexes: Synthesis, Structure, Luminescence, Transformation of Configuration, and Nuclearity Induced by the Acetylacetone Anion

Inorganic Chemistry, Год журнала: 2023, Номер 62(25), С. 9945 - 9963

A flexible polydentate Salamo-Salen-Salamo hybrid ligand H4L was designed and synthesized, which has rich pockets (salamo salen pockets) so that it may have fascinating coordination patterns with transition metal(II) ions. Four multinuclear complexes, novel butterfly-shaped homotetranuclear [Ni4(L)(μ1-OAc)2(μ1,3-OAc)2(H2O)0.5(CH3CH2OH)3.5]·4CH3CH2OH (1), helical homotrinuclear [Zn3(L)(μ1-OAc)2]·2CH3CH2OH (2), double-helical [Cu2(H2L)2]·2CH3CN (3), mononuclear [Ni(H2L)]·1.5CH3COCH3 (4), been synthesized characterized by single-crystal X-ray diffraction. The effects of different anions [OAc- (O2C5H7)2-] on the complexation behavior ions were studied UV-vis spectrophotometry. fluorescent properties four complexes zebrafish, are expected to be a potential light-emitting material. Ultimately, interaction region indicator (IRI) valuations, Hirshfeld surface analyses, density functional theory (DFT & TD-DFT), electrostatic analyses (ESP), simulations carried out further demonstrate weak interactions electronic free its complexes.
