| Abstract: | The reaction of 4-amino-5-ethyl-2H-1,2,4-triazole-3(4H)-thione (AETT, L1) with 2-thiophen carbaldehyde in methanol leads to the corresponding Schiff-base HL1a. The reaction of L1 with AgNO3 in ethanol gives the ionic complex [{[Ag(L1)]NO3}2]n (1). The ionic complex [(PPh3)2Ag(HL1a)2]NO3 · CH3CN (2) can be obtained by the reaction of HL1a with [(PPh3)2Ag]NO3 in methanol and acetonitrile solution, while its reaction with [(PPh3)2PdCl2] in the presence of sodium acetate in methanol leads to the neutral complex [(PPh3)2Pd(L1a)2] · 4MeOH (3). All the compounds were characterized by infrared spectroscopy, elemental analyses as well as by X-ray diffraction studies. |
