Abstract:The reaction of [(Ph3P)2CuCl]2 with 4‐amino‐6‐methyl‐1,2,4‐triazine‐thione‐5‐one (AMTTO, 1 ) in methanol and further recrystallization from methanol/acetone solution gives [(C4H4N3SON(=CMe2)Cu(PPh3)2Cl] ( 2 ) as a neutral complex. [(C4H4N3SON(=CMe2)Ag(PPh3)2]NO3 ( 4 ) can be obtained in excellent yield by the reaction of [(AMTTO)2Ag]NO3 ( 3 ) with triphenylphosphane in methanol/acetone. Both complexes were characterized by infrared spectroscopy, elemental analyses as well as by X‐ray diffraction studies. Crystal data for 2 at –80 °C: space group P1 with a = 1233.8(1), b = 1389.7(1), c = 1417.1(1) pm, α = 89.36(1)°; β = 65.10(1)°, γ = 65.95(1)°, Z = 2, R1 = 0.0582 and for 4 at –80 °C: space group P1, with a = 1193.3(1), b = 1308.5(1), c = 1385.3(1) pm, α = 94.69(1)°, β = 109.14(1)°, γ = 93.42(1)°, Z = 2, R1 = 0.0716.
