摘　　要：One novel manganese(Ⅱ) complex [Mn2(α-Furacrylic radical)4(phen)2(H2O)]·H2O with α-furacrylic acid radical and 1,10-phenanthroline has been synthesized and characterized. Crystal data for this complex:monoclinic,space group C2/c,a=1.082 34(16)nm,b=2.445 8(4) nm,c=1.857 4(3) nm,β=104.353(2)°,V=4.763 5(12) nm3,Dc=1.471 g·cm-3,Z=4,F(000)=2 168. Final GooF=1.004,R1=0.039 7,wR2=0.108 7. The crystal structure shows that two neighboring manganese(Ⅱ) ions are linked together by two bridging α-furacrylic acid radicals and one bridging water molecule,forming a cage structure. The Mn(1)…Mn(1A) bond distance is 0.357 6 nm. Each manganese(Ⅱ) ion is coordinated with two nitrogen atoms of one 1,10-phenanthroline molecule and four oxygen atoms from three α-furacrylic acid radicals and one water molecule,forming distorted octahedral coordination geometry. Thermal stability of the complex was also discussed.One novel manganese（Ⅱ） complex [Mn2（α-Furacrylic radical）4（phen）2（H2O）]·H2O with α-furacrylic acid radical and 1,10-phenanthroline has been synthesized and characterized.
