| 摘 要： | 1 INTRODUCTION Palladium (Ⅱ) coordination and organometallic compounds usually show square planar environments at the metal center1], and have experienced an im- portant development in the past years due to their acting as intermediates in different types of catalytic reactions and numerous applications in organic synthesis2]. Although palladium plays an increase- ingly recognized role as a biometal3], little is known about the structure and function of palladium compounds in living …

Synthesis and Structural Characterization of Pd[CH3O(O)C6H3CHNNC(S)NH2](C5H5N) |

| Abstract: | The reaction of palladium chloride with isovanillin semithiocarbazone (VSTC),CH3O(OH)C6H3CH=NNC(S)NH2, in a mixed solvent of ethanol, pyridine and water yielded the mononuclear palladium(Ⅱ) complex PdCH3O(O)C6H3CHNNC(S)NH2](C5H5N), and its singlecrystal structure was determined by X-ray diffraction. The crystal belongs to triclinic, space group P1-with a = 7.715(4), b = 9.809(6), c = 10.612(4) , α = 93.54(4), β = 111.00(3), γ= 95.92(5)°, V =745.0(7) A3, Mr= 408.75, Z = 2, Dc= 1.822 g/em3, t= 1.397 mm-1, and F(000) = 408. The final R =0.0568 and wR = 0.1439 for 2616 observed independent reflections with Ⅰ＞ 2.0σ(Ⅰ). It was revealed that the palladium atom is bound to a tridentate donor ligand and a pyfidine in a planar square arrangement. The sulphur-nitrogen-oxygen donor of the Schiff-base ligand in the thiol form rather than the thione one is coordinated to the palladium atom via the mercapto sulphur, the β-nitrogen and the hydroxylate oxygen atoms. |
