摘要:利用六亚甲基四胺分別与苯氧乙酸、Cu(NO?3H10及2,4-二氯苯氧乙酸、Zn(NO2)2?6H10反应,得到了2个新的一维配
位聚合物,Cu(pa) al(uhm)}n(1)和( ([ Zns(dcpa)A(OH)l(Al-depa)a(u-hmno-5H1O)n(2)(Hpa=苯氧乙酸, Dcpa-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、红外光谐、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Cul(COOJ双核结构,相邻的[Cu2(COO)双核单元由六亚甲基四胺桥联成一维的

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。

Abstract:Two1DcoodinationpolymersoflCuapa)l(ua-hml}n(1)and{IZna(dcpa)(OHl(Hkzdcpa),(zrhmt}
5H20),()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 3H20, or 2,4-
dichlorophenoxy acetic acid and Zn(NO: )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 Cu*ions are bridged by four pa ligands to form a[ Cu2(COO)] unit, and the neighboring
[Cu(C00) units are further connected by hmt ligands to form a 1D zigzag chain; while in complex 2, six Zn
ions are bridged by six dcpa and two OH ligands to form hexanuclear (Zn (dcpa) (h-o)( -dcpa) subunits
which are further connected by hmt ligands to form a ID double chain. CCDC: 1469683, 1; 1469684, 2.
