The reaction of 4-amino-5-methyl-2H-1,2,4-triazole-3(4H)-thione (AMTT, 1) with 4-methoxy benzaldehyde and 3-methoxybenzaldehyde in methanol led to the iminic derivatives 4-(4-methoxybenzylideneamino)-5-methyl-2H-1,2,4-triazole- 3(4H)-thione (2, L1) and 4-(3-methoxybenzylideneamino)-5-methyl-2H-1,2,4- triazole-3(4H)-thione (3, L2). The reaction of the latter with [(PPh 3)2CuCl] in methanol solution gave the first Cu I complex of 3, [(PPh3)2CuCl(L2)] (4) and in chloroform solution the complex [(PPh3)2CuCl(L2)] ·2CHCl3 (5). All compounds were characterized by infrared spectroscopy, elemental analyses as well as by X-ray diffraction studies.
