Abstract
Specific features of the reaction of anhydrous PtCl4 with 18-crown-6 in anhydrous solvents with different donor and solvating abilities, such as nitromethane, acetonitrile, and 1,2-dichloroethane, under an inert atmosphere are studied. Ionic platinum complexes with oligoethylene glycols or with crown ethers, formed by macroring opening and/or fragmentation under the action of the acidic agent, were isolated. The 1H NMR, IR, and Raman spectra of the complexes were studied. To assess the coordination mode of the crown ether cleavage product with Pt(IV), quantum-chemical calculations at the density functional theory level were carried out.
