摘要
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,Dcalc=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.
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）, 13 =97.497 （6）, γ= 92. 948 （ 5 ）°, V = 1117.9 （4） A^3, Z = 2, Dcalc = 1. 365 g/cm^3, F （000） = 492. In the crystal there were two in- dependent 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.
