本文以5-溴间苯二甲酸(H2BIPA)、1,2-双(4-吡啶基)乙烷(bpe)和Cu(NO3)2·3H2O水热反应得到了一个配位聚合物{[Cu2(BIPA)2(bpe)2]·H2O}n.并用元素分析、红外光谱以及X-射线单晶洐射对其进行了表征.该晶体属三斜晶系,P-1空间群.Cu(Ⅱ)离子通过2个BIPA配体桥联形成一维梯状链,再通过bpe配体连接成二维层状结构.变温磁化率显示羧酸桥联的双核铜之间存在弱的反铁磁相互作用.%A new 2D coordination polymer of {[Cu2(BIPA)2(bpe)2]·H2O}n (1) (H2BIPA=5-bromoisophthalic acid and bpe=1,2-bis(4-pyridyl)ethane) has been prepared and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The crystal is of triclinic, space group P-1 with a=0.951 2(1) nm, b=1.011 5(1) nm,500, Goof=1.022, R1=0.052 7, ωR2=0.114 9. Complex 1 consists of one-dimensional [Cu(BIPA)]n chains that are further bridged by trans-bpe into a two-dimensional layer structure. Magnetic data for 1 show a weak antiferromagnetic interaction between the two Cu(Ⅱ) ions with J=-1.54 cm-1.
