四氯合钯(Ⅱ)酸双{[4-溴-2，6-二(N，N-二乙基氨基亚甲基)吡啶基]氯化钯(Ⅱ)}的合成及晶体结构

A palladium（Ⅱ） complex, [PdLCl]2· [PdCl4], [L=4-bromo-2,6-bis（N,N-diethylaminomethylene）pyridine], was synthesized and its crystal structure was determined by X-ray analysis. The complex crystallizes in monoclinic system with space group Cc, a=0.845 1（17） nm, b=1.836 5（4） nm, c=2.715 8（5） nm,β=93.99（3）°, V=4.204 8（15） nm^3, Z=4, R,=0.037 7 and wR2=0.076 9. The coordination geometry of the Pd atom in the cation is a slightly distorted square planar, with one pyridyl N and two N atoms of the diethylamine ligand, together with one Cl atom. The dihedral angle between the square planar （N3PdCl） and the pyridyl ring is 10.3（4）°. CCDC： 623421.
