水热条件下,以磷酸H3PO4和亚磷酸H3PO3与Mn(Ⅱ)盐进行反应,以四甲基氢氧化铵(TMAOH)调节溶液酸度得到三维开放骨架结构化合物[Mn2.5(PO4H)2(OH)(H2O)](1).对化合物1进行了单晶X射线衍射分析、粉末X射线衍射分析(XRD)、元素分析及红外分析(IR).单晶结构分析表明,该化合物属单斜晶系,C2/c空间群,晶胞参数a=1.763 19(7)nm,b=0.915 12(4)nm,c=0.950 74(6)nm,β=96.565(3)°,V=1.524(1)nm3,Z=4,Dc=3.176 g/cm3,Mr=728.66,μ=4.566 mm-1,R=0.024 5,ωR=0.084 8[I〉2sigma(I)].
A new three-dimensional framework,[Mn2.5(PO4H)2(OH)(H2O)](1),was synthesized under the hydrothermal condition.Its structure was determined by single crystal X-ray diffraction analysis and further characterized by XRD,and elemental analysis.The compound 1 crystallizes in monoclinic space group C2/c,with a=1.763 19(7) nm,b=0.915 12(4) nm,c=0.950 74(6) nm,β=96.565(3)°,V=1.524(1) nm3,Z=4,DC=3.176 g/cm3,Mr=1457.32,μ=4.566 mm-1,R=0.024 5,ωR=0.084 8[I〉2sigma(I)].
