双二苯基膦基吡啶钯氯化物的合成和分子结构

Syntheses and Molecular Structure of 2-(Diphenylphosphino) Pyridine Palladium Complex

二苯基膦基吡啶(Ph_2PPy)同氯化钯配位反应得到配合物(Ph_2PPy)_2PdCl_2·0.5CH_2Cl_2,配合物经X衍射测定了晶体及分子结构。该晶体属正交晶系Pcab,a=0.8050(1)nm,b=2.0152(4)nm,c=2.3067(9)nm,Z-4。晶体结构经全矩阵最小二乘修正,得R=0.059。

Bidentate ligand 2-(diphenylphosphino) pyridineresct with palladium ohloride to form a complex(Ph_2PPy)_2PdCl_2·0.5 CH_2Cl_2 and the struoture of which was determined by X-ray diffraction. The complex erystallizedin the orthorhombie spaoe group Pcab with α=0.8050 (1), b=2.0152 (4), c=2.3067 (9) nm. and Z=4. The reliabilityindex R=0.059 were obtained for 1315 independent reflections.
