中文摘要：

氨基酸还原希夫碱HL（N-（4-吡啶甲基）-L-丝氨酸）与CuCl2·2H2O在室温条件通过扩散法合成了配位聚合物{[Cu2（L）2（Cl）2]·H2O}n（I）。采用元素分析、红外光谱、X-射线单晶衍射、粉末衍射和热重分析进行了表征。两个结晶学独立Cu（Ⅱ）包含于其晶体结构中,Cu1为变形八面体CuO2N2Cl2几何构型;Cu2则呈现略有变形的四方锥结构。Cu1和Cu2通过配体L-的吡啶氮原子以及氯离子的桥连作用连接为2D网状结构。变温磁化率实验表明在温度为2300 K,配合物I表现为铁磁性耦合。

英文摘要：

The coordination polymer { [Cu2（L）2（Cl）2]·H2O }n（I） has been synthesized from the reaction of the amino acid reduced Schiff base HL（N-（4-pyridylmethyl）-L-serine） with CuCl2·2H2O at room temperature using diffusion method.The compound was characterized via elemental analysis,FTIR,single-crystal X-ray diffraction,powder X-ray diffraction and thermogravimetric analysis.The crystal structure consists of two crystallographically independent Cu（Ⅱ）.Cu1 possesses a distorted octahedral CuO2N2Cl2 geometry.Cu2 displays a slightly distorted square pyramid geometry.The L-anion via the pyridyl N atom and chloride ion bridge Cu1 and Cu2 to extend into a 2D network structure.Variable temperature magnetic studies show that complex I is ferromagnetic coupling between 300 K and 2 K.
