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=1.598 0(3) nm,b=2.092 5(4) nm,c=0.659 67(13) nm,β=93.06(3)°,V=2.202 7(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 P21/c, with a=1.598 0(3), b=2.092 5(4), c=0.659 67(13) nm, β=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.
