The six-coordinate bis(pyridine)bis(lawsone) copper(II) complex, Cu(py) (Lw) ,has been syn-
thesized and its structure determined by three dimensional X-ray diffraction data. The complex crystallized
witn one tormuia unit in the triclinic space group (方程式無法摘錄) witn a=8.4847(12), b=8.9940(4). c=l0.0190(4)A,
and α=73.224(4), β=86.302(9), γ=60.900(9)?. The final agreement makes on F,based on the least-
squares refinement of 218 variables for 2290 observations F≧3σ(F), are R=0.041, R =0.046. The bond
pattern of the planar lawsone anion has been found to exhibit some extent of delocalization. The co-
ordinate geometry of the Cu(II) is found to be a tetragonal distorted octahedron with two pyridine nitrogen
atoms and two hydroxy oxygen atoms as the square base and two carbonyl oxygen atoms as the apex. The
bond distances of Cu-N, Cu-0 (hydroxy), Cu-0 (carbonyl) are 2.039(3), 1.945(2),and 2.454(2)A, respec-
tively.
