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 hydrothennally 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 onedimensional dual chains structure with Pht-Mn-Medpq as building units.CCDC∶ 867320.
