摘　　要：采用水热法合成了一个配位聚合物{[Mn(Pht)(Medpq)(H2O)].0.25nH2O}n(Pht=phthalate,Medpq=2-methyldipyrido[3,2-f:2′,3′-h]quinoxaline)1,并对其进行了元素分析、红外光谱、热重表征、磁性表征和X射线单晶衍射测定。配位聚合物1属于单斜晶系,空间群为P21/c。晶胞参数为:a=1.5980(3)nm,b=2.0925(4)nm,c=0.65967(13)nm,β=93.06(3)°,V=2.2027(8)nm3。在晶体中,锰原子与4个氧原子和2个氮原子形成六配位的畸变的八面体构型。整个晶体由Pht-Mn-Medpq单元组成一维双链结构。Abstract： A coordination polymer {[Mn（Pht）（Medpq）（H2O）]·0.25nH2O}n （Pht=phthalate, Medpq=2-methyldipyrido [3,2-f：2＇ ,3＇-h]quinoxaline） 1 has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG, magnetic susceptibility measurements and single-crystal X-ray diffraction. Polymer 1 crystallizes in the monoclinic system, space group P2 1/c, with a=1.598 0（3）, b=2.092 5（4）, c=0.659 67（13） nm, 13= 93.06（3）°, V=2.202 7（8） nm3. In the crystal structure, the manganese atom is six-coordinated with four oxygen atoms and two nitrogen atoms, showing a slightly distorted octahedral geometry. Furthermore, it exhibits a one-dimensional dual chains structure with Pht-Mn-Medpq as building units. CCDC： 867320.
