Coordination Chemistry of Sulfonyl Amides. 2 The Crystal Structure of Copper(II) and Silver(I) Complexes ofN, N‐4‐Toluenesulfonyl‐2‐Pyridylaminato Ligand

摘要

AbstractThree structures containing the N,N‐4‐toluenesulfonyl‐2‐pyridylaminato ligand are presented. The brown crystal of Cu2L4(L =N,N‐4‐toluenesulfonyl‐2‐pyridylaminato) was found to crystallize in the monoclinic space group P2,/c with a = 15.762(12), b = 15.552(5), c = 20.505(11) Å, β = 104.14(7)°; V = 4874(5) Å3;Z = 4; the final RF= 0.050, RWF= 0.049 for 5142 observed reflections and 612 variables. The Cu‐Cu distance is small, 2.516(2) Å and the complex is diamagnetic at room temperature. The colorless crystal of Ag2L was found to crystallize in the monoclinic space group P2t/n with a = 9.620(2), b = 5.625(2), c − 23.250(3) Å, Å = 94.72(1)°; V = 1254.0(5) Å3; Z = 2; the final RF= 0.027; RWF= 0.028 for 1929 observed reflections and 164 variables. The Ag‐Ag distance is 2.739(1) Å The greencrystalof CuL2(py)2was found to crystallize in the monoclinic space group P21with a = 9.366(2), b = 20.615(7), c = 9.862(2) Å,β = 116.73(2)°; V = 1700.5(8) Å3; Z = 2; the final RF= 0.037; RWF= 0.038 for 1636 observed reflections and 423 variables.
