Abstract
The principle possibility of obtaining condensation products R-benzoic aldehyde (R = H, 4-N(CH3)2, 2-OH) and zwitterionic complexes of SnCl4with hydrazides 2- and 4- aminoben-zoic acids. It is proved (IR, mass spectrometry, thermal gravimetric analysis, conductivity), that in the complexes that are formed, аlso implemented enol form of the ligand (hydra- аlso implemented enol form of the ligand (hydra- lso implemented enol form of the ligand (hydra-zone). In the case of bidentate coordination (R = H, 4-N(CH3)2) remains the coordinating node {SnCl4ON}-, which is characteristic for hydrazide complexes and when tridentate (R = 2-OH) – it varies {SnCl3O2N}-.
