摘　　要：利用六亚甲基四胺分别与苯氧乙酸、Cu(NO_3)_2·3H_2O及2,4-二氯苯氧乙酸、Zn(NO_3)_2·6H_2O反应,得到了2个新的一维配位聚合物,{[Cu_2(pa)_4](μ_2-hmt)}_n(1)和{{{[Zn_3(dcpa)_4(OH)]_2(μ_2-dcpa)_2}(μ_2-hmt)}·5H_2O}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Cu^(2+)形成[Cu_2(COO)_4]双核结构,相邻的[Cu_2(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Zn^(2+)形成六核{[Zn_3(dcpa)_4(μ_3-OH)]2(μ_2-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。Two 1D coordination polymers of {[Cu2（pa）4]（μ2-hmt）}, （1） and {{{[Zn3（dcpa）4（OH）12（μ2-dcpa）2}（μ2-nmt）}· 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 Cn^2＋ 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 hint ligands to form a 1D zigzag chain; while in complex 2, six Zn^2＋ 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 hint ligands to form a 1D double chain.
