SYNTHESIS, STRUCTURE AND MAGNETIC PROPERTIES OF THE PHENANTHROLINE BINUCLEAR COPPER (Ⅱ) COMPLEXES BRIDGED BY 1,1,2,2-TETRAACETYLETHANATO(2-) (TAE^2- )

合成了两个以１，１，２，２－四乙酰基乙烷阴离子（ＴＡＥ２－ ）为桥联的双核铜配合物（Ｃｕｐｈｅｎ）２ＴＡＥ（ＣｌＯ４）２·４Ｈ２Ｏ（Ⅰ）和［（ｐｈｅｎＣｕ）（ｐｈｅｎＣｕＣｌ）ＴＡＥ］（ＣｌＯ４）·４Ｈ２Ｏ（Ⅱ），并进行表征。对配合物（Ⅱ）进行了Ｘ－射线晶体结构分析，该配合物属于单斜晶系，空间群为Ｃ２／ｃ（Ｎｏ．１５），晶胞参数为ａ＝ ２５．４６５（５），ｂ＝ １３．０６４（３），ｃ＝ １２．１２５（２），β＝ １１０．７２（３）°，晶胞体积Ｖ＝ ３７７３（２）３， Ｚ＝４，最终偏离因子Ｒ＝ ０．０７０， Ｒｗ ＝ ０．０７４。

The crystal structure of (1,1,2,2 Tetraacetylethanato (2-) bis (phenanthrolinecopper (Ⅱ)) perchlorate chloride tetrahydrate [(phenCu)(phenCuCl)TAE](ClO 4)·4H 2O(Ⅱ) has been determined. This compound belongs to the monoclinic space group C 2/c(No.15), with a=25.465(5),b=13.064(3),c=12.125(2),β=110.72(3)°, V=3773(2) 3 , Z=4 and the final residue factor R=0.070, R w=0.074. The study of magnetic properties shows that antiferromagnetic interaction ( J =-1.05 cm -1 ) is operative in solid sample of the complex (Ⅰ).
