Thiosemicarbazone Structures Including Nickelophilic Interaction as Well as Both Hydrogen Bonding and π-π Stacking Interactions: NLO, Electrochemical, Chromism, and Spectroelectrochemical Properties.

ABSTRACT: Nickelophilic complexes were formed from salicylaldehyde thiosemicarbazone and nitro-substituted aniline through second-sphere coordination interactions. The structures of the complexes were characterized by elemental analysis, IR, ¹H NMR, UV-vis spectroscopy, and single-crystal X-ray diffraction. Additionally, the structural, spectroscopic, electronic, and solvatochromic properties were investigated, and the nonlinear optic properties were studied using density functional theory (DFT) calculations and diffuse reflectance spectroscopy. The energy gap values suggested that the complexes exhibited semiconductor-like behavior. X-ray crystallographic studies revealed that the two phenolato oxygen atoms and two azomethine nitrogen atoms of the doubly deprotonated ONNO tetradentate Sc
