The reaction of [(AMTTO)PdCl 2 ] ( 1 ) (AMTTO = 4‐Amino‐6‐methyl‐1,2,4‐triazine‐3(2H)‐thione‐5‐one) with triphenylphosphane and sodium thiocyanate led to the air‐stable crystalline complexes [(AMTTO)Pd(PPh 3 )Cl]Cl · MeOH ( 2 ) and [(AMTTO)Pd(SCN) 2 ] · MeCN ( 3 ) in excellent yields. 2 and 3 have been characterized by IR and 31 P NMR spectroscopy, elemental analyses as well as X‐ray diffraction studies. Crystal data for 2 at –83 °C: monoclinic, space group P2 1 /n, with a = 974.4(1), b = 988.6(1), c = 2750.7(2) pm, β = 98.16(1)°, Z = 4, R 1 = 0.0241 and for 3 at –80 °C: orthorhombic, space group P2 1 2 1 2 1 , with a = 972.0(3), b = 1168.1(4), c = 1316.6(1) pm, Z = 4, R 1 = 0.0817.
