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 αΈΎeOH (2) and [(AMTTO)Pd(SCN) 2 ] Β΄MeCN (3) in excellent yields. 2 and 3 have been char
The title compounds were prepared from the elements by reactions in sealed tantalum tubes in a high-frequency furnace. Their structures were re5ned from single crystal X-ray di4ractometer data: Pnma, a β«Ψβ¬ 744.4(1) pm, b β«Ψβ¬ 434.15(9) pm, c β«Ψβ¬ 845.5(1) pm, wR2 β«Ψβ¬ 0.0433, 658 F 2 values, 20 variabl
The crystal structures of Ni(NCNH 2 ) 4 Cl 2 and Co(NCNH 2 ) 4 Cl 2 , the first complexes with cyanamide as a neutral ligand, have been determined from single crystal data (Im3m, Z = 6, a = 1259.3(2) pm, R 1 = 0.0245 for Ni(NCNH 2 ) 4 Cl 2 and a = 1266.3(2) pm, R 1 = 0.0241 for Co(NCNH 2 ) 4 Cl 2 ;
