以金属铜和3,5-二叔丁基-1,2-苯醌(3,5-DBBQ)为原料,在吡啶溶液中合成了Cu(py)2(3,5-DBCat)。作为吡啶溶剂化物获得的络合物的晶体学表征(三斜晶系,P1,a=13.909(2)A,B= 14,187(2)A,c= 14,570(3)A,75.26(1)o,β= 72,37(1)o,γ=80.57(1)o,V=2637.9(9)A3,Z=2)已经表明该分子是二聚体,其中四方锥金属离子通过儿茶酚配体的氧原子在基部位置桥接
Cu(py) 2 (3,5-DBCat) has been prepared by reacting copper metal with 3,5-di-tert-butyl-1,2-benzoquinonc (3,5-DBBQ) in pyridine solution. Crystallographic characterization of the complex obtained as the pyridine solvate (triclinic, P1, a=13.909(2) A, b=14,187(2) A, c=14,570(3) A, 75.26(1) o , β=72,37(1) o , γ=80.57(1) o , V=2637.9(9) A 3 , Z=2) has shown that the molecule is dimeric with square pyramidal metal ions bridged at basal positions by oxygen atoms of the catecholatc ligands
