【摘要】 利用六亚甲基四胺分别与苯氧乙酸、Cu（NO₃）₂·3H₂O及2,4-二氯苯氧乙酸、Zn（NO₃）₂·6H₂O反应,得到了2个新的一维配位聚合物,{[Cu₂（pa）₄]（μ₂-hmt）}_n（1）和{{{[Zn₃（dcpa）₄（OH）]₂（μ₂-dcpa）₂}（μ₂-hmt）}·5H₂O}n（2）（Hpa=苯氧乙酸,Hdcpa=2,4-二氯苯氧乙酸,hmt=六亚甲基四胺）。2个配合物均用元素分析、红外光谱、X射线单晶衍射及差热分析进行了表征。晶体结构分析表明,在配合物1中,4个苯氧乙酸根桥联2个Cu²⁺形成[Cu₂（COO）₄]双核结构,相邻的[Cu₂（COO）₄]双核单元由六亚甲基四胺桥联成一维的"zigzag"链;在配合物2中,6个2,4-二氯苯氧乙酸根和2个OH^-桥联6个Zn²⁺形成六核{[Zn₃（dcpa）₄（μ₃-OH）]2（μ₂-dcpa）₂}结构单元,然后相邻的六核单元由2个六亚甲基四胺桥联成一维双链结构。更多还原

【Abstract】 Two 1D coordination polymers of {[Cu₂（pa）₄]（ μ₂-hmt）}_n（1） and {{{[Zn₃（dcpa）₄（OH）]₂（ μ₂-dcpa）₂}（ μ₂-hmt）}·5H₂O}_n（2）（Hpa=phenoxyacetic acid, Hdcpa=2,4-dichlorophenoxy acetic acid, hmt=hexamethylenetetramine） were obtained by the reactions of hexamethylenetetramine with phenoxy acetic acid and Cu（NO₃）₂·3H₂O, or 2,4-dichlorophenoxy acetic acid and Zn（NO₃）₂·6H₂O, respectively. The complexes were characterized by elemental analysis, IR, single X-ray diffraction and thermogravimetric analyses. The crystal structural analysis revealed that, in complex 1, two Cu²⁺ ions are bridged by four pa ligands to form a [Cu₂（COO）₄] unit, and the neighboring[Cu₂（COO）₄] units are further connected by hmt ligands to form a 1D zigzag chain; while in complex 2, six Zn²⁺ ions are bridged by six dcpa and two OH-ligands to form hexanuclear {[Zn₃（dcpa）₄（ μ₃-OH）]₂（ μ₂-dcpa）₂} subunits which are further connected by hmt ligands to form a 1D double chain.更多还原
