摘      要：A new Cu(Ⅱ) complex,[Cu_(4)Cl_(6)O(1-TrTz)_(4)]where 1-TrTz is 1-trityl-1H-[1,2,4]triazole,was synthesized by the reaction of 1-trityl-1H-[1,2,4]triazole with two hydrated cupric chlorides,and its structure was characterized by X-ray single-crystal diffraction.[Cu4Cl6O(1-TrTz)4]is of monoclinic system,space group P21/c,a=12.5024(13),b=26.400(3),c=28.588(3)A,β=112.807(4)°,V=8698.1(16)A^(3),Z=4,ρcalc=1.411 g/cm^(3),μ=1.265 mm^(–1),F(000)=3772,the final R=0.1293 and w R=0.3644 for 55774 observed reflections (I2s(I)),R(all data)=0.1972,w R(all data)=0.3989,completeness to theta of 25.242 is 99.9%and GOF=*** the structure of[Cu_(4)Cl_(6)O(1-TrTz)_(4)],the central O atom is tetrahedral and is coordinated with four Cu *** distance between copper and oxygen bond is 1.909(6)*** addition,the catalytic property of this complex was investigated and it could effectively catalyze the Ullmann coupling reaction of various (hetero)aryl chlorides with azoles.
