[Mg(H-Sulf)(H2O)5](H-Sulf)·5H2O的合成、晶体结构和谱学表征
  • 摘要

    柳氮磺胺吡啶(H3-Sulf)与氢氧化镁反应得到化合物[Mg(H-Sulf)(H2O)5](H-Sulf)·5H2O.用元素分析、Uv-Vis、荧光、IR光谱和单晶X-射线衍射方法对该化合物进行表征.化合物的化学式:C36H46MgN8O20S2,Mr=999.24,三斜晶系,P-1空间群,晶胞参数;a=1.115 16(13)nm,b=1.544 71(19)nm,c=1.604 71(19)nm,α=115.654(2)°,β=107.909(2)°,γ=91.861(2)°,V=2.326 4(5)nm3,Z=2,Dc=1.426 Mg/m3,R1=0.130,wR2=0.259(I>2σ(I),S=1.048.化合物为离子型化合物,由阳离子[Mg(H-Sulf)(H2O)5]+,阴离子[H-Sulf]-和5个结晶水组成.其中心金属Mg(Ⅱ)离子采取六配位变形的八面体几何构型,周围被5个H2O和1个来自柳氮磺胺吡啶的单齿配位的羧基O所包围,羟基和吡啶N均未参与配位.化合物通过复杂的分子内和分子间氢键作用形成三维的超分子结构.
