摘要

The reaction of of 4-amino-5-ethyl-2H-1,2,4-triazole-3(4H)-thione (AETT, L) with furfural in methanol led to the corresponding Schiff-Base (L1). The reaction of L1 with [Cu(PPh3)(2)]Cl in methanol gave to the neutral compound [(L1)Cu(PPh3)(2)Cl] (1). By recrystallization of 1 from CH3CN the complex [(L1)Cu(PPh3)(2)Cl]center dot CH3CN (1a) was obtained. All compounds were characterized by infrared spectroscopy, elemental analyses as well as by X-ray diffraction studies. Crystal data for L1 at -80 degrees C: space group P (1) over bar with a = 788.4(1) b = 830.3(2), c = 928.8(2) pm, alpha = 84.53(1)degrees, beta = 65.93(1)degrees, gamma = 72.02(1)degrees Z = 2, R-1 = 0.0323; for 1 at -100 degrees C: space group P (1) over bar with a = 1166.3(1), b = 1423.8(2), c = 1489.1(2)pm, alpha = 62.15(1)degrees, beta = 72.04(1)degrees, gamma = 88.82(1)degrees, Z = 2, R-1 = 0.0338 and for 1a at -100 degrees C: space group P2(1)/c with a = 1294.1 (1), b = 1019.8(2), c = 3316.9(4) pm, beta = 94.73(1)degrees, Z = 4, R-1 = 0.0435.
