Synthesis, Structural\nCharacterization, and Theoretical\nAnalysis of Nonconventional Bonding in Dinuclear Zinc(II) Complexes\nwith Tridentate Schiff Bases

Two tridentate N,N,O-donor\nligands, HL<sup>1</sup> =\n4-chloro-2-(((2-(methylamino)ethyl)amino)methyl)phenol\nand HL<sup>2</sup> = 4-chloro-2-(((2-(dimethylamino)ethyl)amino)methyl)phenol,\nhave been used to synthesize phenolate-bridged dinuclear complexes\n[Zn<sub>2</sub>(L<sup>1</sup>)<sub>2</sub>Cl<sub>2</sub>] (<b>1</b>) and [Zn<sub>2</sub>(L<sup>2</sup>)<sub>2</sub>(N<sub>3</sub>)<sub>2</sub>] (<b>2</b>). Single-crystal X-ray diffraction analysis\nconfirmed their structures. Both complexes form assemblies in the\nsolid state. Moreover, the existence of nonconventional spodium bonds\nin <b>1</b> and tetrel bonds in <b>2</b> has been explored\nusing theoretical calculations, including MEP surface plots and QTAIM\nand NCIplot analyses.
