【摘要】 合成了配合物［ＭＬ］３［Ｃｒ（ＣＮ）６］２·ｘＨ２Ｏ（Ｍ二Ｎｉ，Ｌ＝三（２－胺基乙基）胺（ｔｒｅｎ），ｘ＝ Ｏ； Ｍ＝ Ｃｕ， Ｌ＝二丙烯三胺（ ｄｐｔ）， ｘ＝ ８）和［ Ｍ（ ｔｎ）２］２［Ｃｒ（ ＣＮ）６ ］ＣＩＯ４· ＸＨ２ Ｏ（ ｔｎ＝ １， ３－丙二胺，Ｍ＝ Ｎｉ，ｘ＝ Ｏ；Ｍ＝ Ｃｕ，ｘ＝ ２）．用元素分析、ＩＣＰ分析、ＩＲ光谱等对配合物进行了表征，测定了它们的磁性质．变温磁化率研究表明：［Ｃｕ（ｄｐｔ）］３［Ｃｒ（ＣＮ）６］２·８Ｈ２Ｏ中存在弱的铁磁（Ｔ＞ １６．６３Ｋ）和反铁磁（Ｔ＜ １６．６３Ｋ）相互作用；［Ｃｕ（ｔｎ）２］２［Ｃｒ（ＣＮ）６］ＣＩＯ４·２Ｈ２Ｏ中存在反铁磁相互作用（Ｔ＜５．８６Ｋ）．研究发现，这些配合物有两种结构类型：氰基桥联结构和双配合盐结构．更多还原

【Abstract】 Novel complexes of the type[ ML]3 [ Cr(CN)6 ]2 xH2 O (M = Ni, L = Tris(2-aminoethyl) amine(tren), x = 0; M = Cu, L = dipropylenetriamine(dpt), x = 8) and [ M(tn)2 ]2, [ Cr(CN)6] CIO4’ xH2O (tn = 1, 3-propanediamine . M = Ni, x = 0; M = Cu, x = 2)have been prepared and studied by elemental anal- yses, IR spectra and magnetic measurements. Three of the complexes have been characterized by temperature - dependent magnetic susceptibilities, weak ferromagnetic and antiferromagnetic exchange interaction was found for [ Cu(dpt) ]3 [ Cr(CN)6 ]2 8H2 O, and antiferromagnetic exchange interaction was found for [ Cu (tn)2 ]2 [ Cr(CN)6 ]CIO4 2H2 O. Physico-chemical studies account for two structure types of complexes: the polymeric structure, with cyanide bridges between Cu or octahedral Ni and octahedral Cr, and double com- plex salt.更多还原
