Synthesis, Characterization and Crystal Structure of 4‐Amino‐1,2,4‐Δ 2 ‐triazoline‐5‐thione and its Silver(I) Complex

The reaction of 4‐amino‐1,2,4‐Δ 2 ‐triazoline‐5‐thione (ATT, 1 ) with AgNO 3 in methanol led to the complex [Ag(ATT) 2 ]NO 3 ( 2 ). 2 was characterized by elemental analyses, 1 H NMR, IR, and Raman spectroscopy as well as single‐crystal X‐ray diffraction. The molecular structure of 1 was also determined by single crystal X‐ray analysis. Crystal data for 1 at −80 C: space group C2/c with a = 2107.4(2), b = 1425.1(1), c = 688.4(1) pm, β = 104.55(1)°, Z = 16, R 1 = 0.0514, crystal data for 2 at −80 °C: space group P2 1 /c with a = 675.7(1), b = 1321.1(1), c = 1311.2(1) pm, β = 90.03(1)°, Z = 4, R 1 = 0.0437.
