The reaction of 4‐amino‐5‐methyl‐2H‐1,2,4‐triazole‐3(4H)‐thione (AMTT, 1 ) with AgNO 3 and triphenylphosphane in a molar ratio 1:1:2 in ethanol led to the dimeric complex {[Ag(AMTT)(PPh 3 ) 2 ]NO 3 } 2 ·4EtOH ( 2 ). 2 was characterized by elemental analyses, IR, 31 P NMR spectroscopy as well as single crystal X‐ray diffraction. Crystal data for 2 at −80 °C: space group ${\rm P}{\bar 1}$ with a = 1265.5(2), b = 1300.9(2), c = 1509.5(2) pm, α = 83.77(2)°, β = 79.22(2)°, γ = 62.89(2)°, Z = 2, R 1 = 0.0330.
