【Abstract】 The complex[Ni（teta）（NCS）₂]（teta=meso-5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane）was synthesized and characterized by elementary analysis,IR and UV and the structure was determined by single-crystal X-ray diffraction analysis.The result showed the crystal belonged to triclinic,space group P（1） with a=8.0261（17）,b=9.1174（19）,c=15.485（3）（A）?,a=94.438（5）,β=97.497（6）,γ=92.948（5）^o,V=1117.9（4）（A）?³,Z=2,D_calc=1.365g/cm³,F（000）=492.In the crystal there were two independent Ni（Ⅱ）centres.Each Ni（Ⅱ）ion was coordinated by four nitrogen atoms from one teta ligand and two nitrogen atoms from NCS^-anions to form a distorted octahedron geometry.更多还原
