抄録

The bis(trifluoromethanesulfonato)nickel(II) complex with two 2, 2′-bipyridine (bpy), [Ni(bpy)2(CF3SO3)2] (1), and the mono(trifluoromethanesulfonato)palladium(II) complex with bis(2-diphenylphosphinoethyl)phenylphosphine (p3), [Pd(p3)(CF3SO3)](CF3SO3)・C6H6 (2), were isolated. The crystal structures for 1 and 2 have been determined by an X-ray crystal structure analysis. Complex 1 crystallizes in monoclinic space group Aa with a=18.55(1), b=14.48(1), c=9.941(7)A, β=101.98(3)°, and Z=4. Complex 2 crystallizes in the monoclinic space group P21/n with a=17.211(5), b=27.175(7), c=9.962(2)A, β=105.66(2)°, and Z=4. The crystal of 1 contains a distorted octahedral nickel(II) complex with a cis arrangement, and the crystal of 2 contains a distorted square-planar palladium(II) complex. The metal-oxygen bond distances for triflate (CF3SO3-), (2.135(5) and 2.148(4)A for 1 and 2.126(7)A for 2), are comparable to those for the other oxygen donors. Three S-O bond distances in the coordinated triflate are close to one another. The stability of the metal-oxygen bond is discussed in terms of the electronic property of triflate.
