| Abstract: 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. CCDC: 703674. |
