✦ Synopsis

The reaction of [(AMTTO)PdCl 2 ] (1) (AMT-TO = 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 ḾeOH (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, b = 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.
