二硫代草酰胺基或二环己酮草酰二腙作桥联基的新型双核Cu（Ⅱ）－Cu（Ⅱ）配合物的合成和磁性（Ⅱ）

Synthesis and Magnetism of New Binuclear Cu(Ⅱ) Cu(Ⅱ) Complexes Bridged by Dithio oxamidate or Biscyclohexanone Oxalyldihydrazone Group (Ⅱ)

合成和表征了四种新的以二硫代草酰胺基（ｄｔＯ２－）或二环己酮草酰二腙（ＢＣＯ）作桥基的双核金属配合物［Ｃｕ２（ｐｈｅｎ）２（ｄｔＯ）］（ＣｌＯ４）２（１）、［Ｃｕ２（ｄｉｅｎ）２（ｄｔＯ）］（ＣｌＯ４）２·２Ｈ２Ｏ（２）、［Ｎｉ２（ｄｉｅｎ）２（Ｈ２Ｏ）２（ｄｔＯ）］（ＣｌＯ４）２（３）及［Ｃｕ２（ｐｈｅｎ）２（ＣｌＯ４）２（ＢＣＯ）］（ＣｌＯ４）２（４），（ｐｈｅｎ：１，１０－邻菲咯啉，ｄｉｅｎ：二乙烯三胺）。测定了配合物１和４的变温磁化率，并求出交换积分Ｊ分别为－７．６７（１）和－０．９２（４）ｃｍ－１，表明双核配合物中铜离子间存在反铁磁性自旋交换相互作用。

Four new binuclear metal complexes, bridged by dithio oxamidate(dtO) group or biscyclohexanone oxalyldihydrazone(BCO) group, Cu 2(phen) 2(dtO)(ClO 4) 2(1), Cu 2(dien) 2(dtO)(ClO 4) 2·2H 2O(2), Ni 2(dien) 2(H 2O) 2(dtO)(ClO 4) 2(3) and Cu 2(phen) 2(ClO 4) 2(BCO)(ClO 4) 2(4), where phen and dien denote 1,10 phenanthroline and diethylenetriamine, respectively, were synthesized and characterized by elementary analysis, IR and electronic spectra. The results from the variable temperature(4.0￣300K) magnetic susceptibility measurement of the complexes 1 and 4 indicate that there exists an antiferromagnetic exchange interaction between the Cu(Ⅱ) Cu(Ⅱ) ions with J(cm -1 ) values of -7.67 (1)and -0.92 4.
