Composition and Structure of Complexes Formed in GeCl4–2-Hydroxybenzene(2-hydroxynaphthaline-1)carbaldehyde Isonicotinoylhydrazone–ZnCl2–Methanol


Tetrachlorozincates [Ge(LH)2][ZnCl4]∙CH3OH were isolated for the first time from isonicotinoylhydrazone 2-hydroxybenzene (2-hydroxynaphyl-1)carbaldehyde (H2L)–GeCl4–ZnCl2–CH3OH systems, in which cations are [Ge(L·H)2]2+ complexes protonated by the pyridine nitrogen atom, with L ligands tridentately coordinated via the azomethine nitrogen atom and oxygen atoms of deprotonated hydroxyazino and hydroxy groups. The complexes were studied using the methods of conductometry, thermogravimetry, IR, and 1H NMR spectroscopy.
