- 中文摘要: Three structures containing the N,N-4-toluenesulfonyl-2-pyridylaminato ligand are presented. The brown crystal of Cu/sub 2/L/sub 4/(L=N,N-4-toluenesulfonyl-2-pyridylaminato) was found to crystallize in the monoclinic space group P2/sub 1//c with a=15 .762(12), b=15.552(5), c=20.505(11).ANG.,.beta.=104.14(7).degree.; V=4874(5).ANG./sup 3/; Z=4; the final R/sub F/=0.050, R/sub WF/=0.049 for 5142 observed reflections and 612 variables. The Cu-Cu distance is small, 2.516(2).ANG., and the complex is diamagnetic at room temperature. The colorless crystal of Ag/sub 2/L/sub 2/ was found to crystallize in the monoclinic space group P2/sub 1//n with a=9.620(2), b=5.625(2), c=23.250(3).ANG.,.beta.=94.72(1).degree.; V=1254.0(5).ANG./sup 3/; Z=2; the final R/sub F/=0.027; R/sub WF/=0.028 for 1929 observed reflections and 164 variables. The Ag-Ag distance is 2.739(1).ANG.. The green crystal of CuL/sub 2/(py)/sub 2/ was found to crystallize in the monoclinic space group P2/sub 1/ with a=9.366(2), b =20.615(7), c=9.862(2).ANG.,.beta.=116.73(2).degree.; V=1700.5(8).ANG./sup 3/; Z=2; the final R/sub f/=0.037; R/sub WF/=0.038 for 1636 observed reflections and 423 variables. A reversible transformation between Cu/sub 2/L/sub 4/ and CuL/sub 2/(py)/ sub 2/ is reported.
