A new one-dimensional mixed-valence Cu（Ⅰ）/Cu（Ⅱ） complex [Cu（bipy）（Me2dtc）CuI2]n 1 （bipy = 2,2′-bipyridine and Me2dtc = N,N-dimethyldithiocarbamate） has been synthesized under solution condition, and chara...A new one-dimensional mixed-valence Cu（Ⅰ）/Cu（Ⅱ） complex [Cu（bipy）（Me2dtc）CuI2]n 1 （bipy = 2,2′-bipyridine and Me2dtc = N,N-dimethyldithiocarbamate） has been synthesized under solution condition, and characterized by elemental analysis, IR spectrum, single-crystal X-ray diffraction and magnetic property. The crystal belongs to the tetragonal system, space group P4122 with a = b = 11.6504（16）, c = 13.466（3） A, V = 1827.8（5） A^3, Z = 4, Dc = 2.389 g/cm^3, Mr = 657.27, λ（MoKa） = 0.71073 , μ = 5.931 mm·1, F（000） = 1236, the final R = 0.0483 and wR = 0.1245. A total of 2102 unique reflections were collected, of which 2009 with I 〉 2σ（I） were observed. 1 consists of polymeric [Cu^II2]nn^- anions and [Cu^II（bipy）（Me2dtc）]^＋ cations. It is interesting that the cations of 1 interact through π-π stacking interactions after rotating 90° to form one-dimensional chains parallel to the anion chains. The magnetic study indicates antiferromagnetic behavior for this complex.展开更多

Its crystal structure has been determined by X-ray diffraction analysis. The crystal belongs to triclinic with space group P1-,a=0.7339(2) nm,b=1.1032(2) nm,c=1.1203(2) nm,α=90.27(3)°,β=102.03(3)°,γ=104.91(3)°,Z=2,V=0.8556(3) nm 3,D_c=1.360 g/cm 3,μ=0.325 mm -1 ,F(000)=368,final R_1=0.0475. The planes of 4-methoxybenzyl group and triazole ring are nearly perpendicular to each other. The dihedral angle is 83.97°. There is an obvious π-π stacking interaction between the molecules in the crystal lattice. The results of biological test show that the title compound has fungicidal and plant growth regulating activities.展开更多
