- 中文摘要: The three-coordinate tris(2-pyridylphosphine) palladium(0) complex is the first example of a group 10 metal complex bearing pyridine substituted phosphine ligand, whose crystal structure is determined, Pd(PPh/sub 2/py)/sub 3/ crystallizes in the triclinic space group P.1bar., with a=12.874(4).ANG., b=14.162(3).ANG., c=14.912(3).ANG.,.alpha.=87.76(2).degree., .beta.=66.50(2).degree.,.gamma.=63.17(2).degree., Z=2, and V=2191(1).ANG./sup 3/. Full-matrix least-squares refinement of 523 variables using 4911 data (F/sub o//sup 2/>3.sigma.F/sub o//sup 2/) gave R=0.033 and R/sub w/=0.033. The pyridine ring is disordered. Possible weak interactions among Ph rings or Py rings and Pd center are discussed. Close approach of the ortho hydrogen on phenyl rings to the Pd center may imply facile ortho metallation.
