The reaction of 2,4,6-tris(2-pyridyl)-1,3,5-triazine(tptz) and K2PdCl4 in THF/H2O(10:1) results in the hydrolysis of tptz to bis(2-pyridylcarbonyl)amide anion(bpca),and affords complex Pd(bpca)Cl 1,which is the first example of Pd(Ⅱ)-promoted hydrolysis of ligands.Crystal data for 1:orthorhombic,space group Pbcn,a=12.0136(17),b=14.180(2),c=6.9747(11) ,V= 1188.2(3) 3,Z=4,Mr=368.06,Dc=2.058 g/cm3,F(000)=720,μ=1.786 mm-1,λ(MoKα)= 0.71073 ,T=293(2) K,2θmax=54.9o,GOOF=1.085,the final R=0.0647 and wR=0.1051 for 1234 observed reflections with I > 2σ(I)(refinement on F2).Complex 1 is connected through hydrogen bonding to give a 2D network.And weak Pd…Pd interactions are also found between adjacent molecules with the distance of 3.6074(5) ,so the complex is further extended into a 3D supramolecular structure.Thermal gravity analysis(TGA) shows that 1 exhibits high thermal stability below 310 ℃.X-ray powder diffraction(XRD) and UV/Vis spectrum of 1 are also discussed.
The reaction of 2,4,6-tris (2-pyridyl) -1,3,5-triazine (tptz) and K2PdCl4 in THF / H2O (10: 1) results in the hydrolysis of tptz to bis (bpca), and affords complex Pd (bpca) Cl 1, which is the first example of Pd (II) -promoted hydrolysis of ligands.Crystal data for 1: orthorhombic, space group Pbcn, a = 12.0136 b = 14.180 (2), c = 6.9747 (11) , V = 1188.2 (3) 3, Z = 4, Mr = 368.06, Dc = 2.058 g / cm3, F -1, λ (MoKα) = 0.71073 , T = 293 (2) K, 2θmax = 54.9o, GOOF = 1.085, the final R = 0.0647 and wR = 0.1051 for 1234 observed reflections with I> 2σ (I) on F2). Complex 1 is connected through hydrogen bonding to give a 2D network. And weak Pd ... Pd interactions are also found adjacent molecules with the distance of 3.6074 (5) , so the complex is further extended into a 3D supramolecular structure .Thermal gravity analysis (TGA) shows that 1 exhibits high thermal stability below 310 ° C. X-ray powder diffraction (XRD) and UV / Vis spectrum of 1 are also discussed.
