СИНТЕЗ И СТРОЕНИЕ НОВЫХ КОМПЛЕКСНЫХ СОЕДИНЕНИЙ ПАЛЛАДИЯ(II) С N-ЗАМЕЩЕННЫМИ ТЕТРАЗОЛАМИ

Abstract

The interaction between palladium(II) chloride and several N-substituted mono- and dinuclear tetrazoles was investigated for the first time. 1-Methyl-, 1-phenyl-, 2-methyl- and 2-tert-butyl-substituted 5-aminotetrazoles as well as 1 (2 hydroxyethyl)tetrazole and 1,5-diaminotetrazole were shown to react with palladium dichloride in water or water-ethanol mixture (рН = 1–2) to give crystalline complexes PdL2Cl2 in high yield. In analogous conditions bis(2-methyltetrazol-5-yl)amine forms complex Pd(HL7)Cl2 while 1,3-bis(2-methyltetrazol-5-yl)triazene and 1,3-bis(2-tert-butyltetrazol-5-yl)triazene deprotonate to give complexes PdLCl. Products were characterized by elemental analysis and IR-spectroscopy. The structure of complex trans-Pd(L1)2Cl2 was established by X-ray analysis.
