Synthesis and Crystal Structure of the Imidazale-bridged Dicopper(II) Complex with Tetraaza Macrocycles

This paper reports the synthesis and structure of the imidazolate-bridged dicopper (Ⅱ) complex with tetraaza macrocycles [μ-C3H5N5-Cu2(C10H24N4)2]Br(ClO4)2·C2H5OH (C10H24N4=1,7-dimethyl-1,4,7,10,-tetraazacyclododecane).

The crystal structure of the complex has been determined by X-ray single crystal diffraction method. The complex crystallizes in the monoclinic space group P2(1)/c with a=8,698(3), b=25.713(7), c=18,075(6)angstrom, ss=102.66(3), V=3944(3)A(3), Z=4, In the [mu-C3H5N5-Cu-2(C10H24N4)(2)](3+) complex ion the two livecoordinated copper( II) ions are in square pyramid enviroment, in which the four nitrogen atoms of tetraaza macrocycle form the basal plane and the nitrogen atom from bridged-imidazole occupies the apex of square pyramid. The axial Cu-N bond lengths (average, 2.059 angstrom) are consistent with the Cu-N bond lengths (average, 2.042 angstrom) which on the basal plane of the square pyramid.SCI(E)中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)010932-9361
