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。
A coordination polymer {[Mn (Pht) (Medpq) (H2O)] was synthesized by hydrothermal method. 0.25nH2O} n (Pht = phthalate, Medpq = 2-methyldipyrido [3,2-f: 2 ’, 3 ’-h] quinoxaline 1 was synthesized and characterized by elemental analysis, IR, TG, magnetic characterization and single crystal X-ray diffraction. Coordination polymer 1 belongs to monoclinic system with space group P21 / c. The unit cell parameters are: a = 1.5980 (3) nm, b = 2.0925 (4) nm, c = 0.65967 (13) nm, β = 93.06 (3) °, V = 2.2027 (8) nm3. In the crystal, the manganese atom forms a hexa-coordinated distorted octahedral configuration with 4 oxygen atoms and 2 nitrogen atoms. The entire crystal consists of one-dimensional double-stranded structure of Pht-Mn-Medpq units.
