| 摘要: 以MnCl2·4H2O,H2DSBA(二硫代水杨酸)和FBIX(2,3,5,6-四氟-1,4-二咪唑基亚甲基苯)为原料,采用水热的方法得到了一个二维配位聚合物[Mn(DSBA)(FBIX)0.5]n。通过元素分析、红外光谱以及X-射线单晶洐射对其进行了表征。该晶体属单斜晶系,P21/c空间群。Mn(Ⅱ)离子通过2个DSBA配体桥联形成一维链状结构,链与链再通过FBIX配体连接成二维层状结构。变温磁化率显示羧酸桥联的双核锰之间存在反铁磁相互作用。 |

| Abstract: A new two-dimensional coordination polymer of [Mn(DSBA)(FBIX)0.5]n (1) (H2DSBA=2,2'-disulfanediyl-dibenzoic acid and FBIX=2,3,5,6-tetrafluoro-1,4-bis(imidazol-1-yl-methyl) benzene) has been prepared and chara-cterized by elemental analysis, IR spectroscopy, TGA and single-crystal X-ray diffraction. The crystal is of monoclinic, space group P21/c with a=1.050 41(12) nm, b=1.160 23(13) nm, c=1.940 36(18) nm, β=116.647(3)°, V=2.113 6(4) nm3, Dc=1.617 g·cm-3, Z=4, F(000)=1 040, Goof=1.052, R1=0.057 9, wR2=0.097 0. Complex 1 shows a two-dimensional layer structure based on paddle-wheel building units. Magnetic-property studies show that antiferromagnetic exchange interactions propagate among the Mn(Ⅱ) ions. CCDC: 834854. |
