| 摘要: 用溶液法和水热法分别合成了2个含2-苯氧基丙酸配体(HL)的聚合物{[NiL2(H2O)2(bipy)]·2H2O}n(1)、{[ZnL2(bipy)]·2H2O}n(2)(bipy=4，4′-联吡啶)，用元素分析、红外光谱、热重和单晶X-射线衍射对产物进行了表征。在化合物1中，镍原子与2个羧基氧原子、2个配位水氧原子及2个4，4′-联吡啶的2个氮原子配位，配位数为6，镍原子的配位构型为畸变的八面体；而在化合物2中，锌原子与2个羧基氧原子及2个4，4′-联吡啶中的2个氮原子配位，锌原子的配位构型为畸变的四面体。在这2个化合物里，4，4′-联吡啶通过氮原子连接金属原子形成一维链状。链间氢键与π-π堆积作用又将一维链链接成二维层状结构。 |

| Abstract: Two coordination polymers based on 2-phenoxypropionic acid（HL, C9H10O3）, {[NiL2(H2O)2(bipy)]·2H2O}n (1) and {[ZnL2(bipy)]·2H2O}n (2) (bipy=4,4′-bipyridine) were synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analyses and single crystal X-ray diffraction. In the complex 1, the metal atoms are coordinated to two carboxylic oxygen atoms, two oxygen atoms from two water molecules and two nitrogen atoms from two 4,4′-bipyridine ligand. The nickel atoms are six coordinated in a distorted octahedron geometry. The zinc atoms are four coordinated to two carboxylic oxygen atoms and two nitrogen atoms from two 4,4′-bipyridine ligand in a distorted tetrahedron environment for complex 2. The 4,4′-bipyridine ligands in both compounds connect the metal atoms into single dimensional chains by nitrogen atoms. Interchain hydrogen bonds and π-π stacking interactions link the 1D chains into 2D layers and strengthen the stability of molecular structure. CCDC: 820470, 1; 820471, 2. |
