摘要
A novel three-dimensional manganese zinc phosphatophosphite [H2CHBMA][Zn1.5Mn(HPO3)2\5(PO4)]\5H2O(TJPU-3Mn) with extra-large twenty-membered ring channels was isolated by 1,3-cyclohexanebis(methylamine) as the template under hydrothermal conditions.Single crystal structure refinement reveals that TJPU-3Mn crystallizes in the monoclinic space group C2/c,with cell parameters,a=3.3929(7) nm,b=1.3045(3) nm,c=0.89713(18) nm,β=104.37(3)°,V=3.8465(13) nm3,Z=2.The connectivities of the ZnO4,MnO4,PO4 and HPO3 groups create a three-dimensional porous architecture with extra-large twenty-membered ring channels intersected by eight-membered rings.It is the first structure analogue to the famous aluminophsphate JDF-20.More interestingly,the diprotonated CHBMA cations in the channel are all in cis configuration,indicating the potential for separation and recognition of CHBMA isomers.Powder X-ray patterns reveal the structure of TJPU-3Mn sustains after the emission of water molecules obtained by calcining at 150 ℃ for 2 h.
Abstract A novel three-dimensional manganese zinc phosphatophosphite [ H2CHBMA ] [ Zn1.5 Mn（ HPO3 ）2·（PO4）]·H2O（TJPU-3Mn） with extra-large twenty-membered ring channels was isolated by 1,3-cyclohexanebis（methylamine） as the template under hydrothermal conditions. Single crystal structure refinement reveals that TJPU-3Mn crystallizes in the monoclinic space group C2/c, with cell parameters, α = 3. 3929 （7） nm, b=1.3045（3） nm, c=0.89713（18） nm,/3=104.37（3）°, V=3.8465（13） nm^3, Z=2. The connectivities of the ZnO4 , MnO4 , PO4 and HPO3 groups create a three-dimensional porous architecture with extra-large twenty-membered ring channels intersected by eight-membered rings. It is the first structure analogue to the famous aluminophsphate JDF-20. More interestingly, the diprotonated CHBMA cations in the channel are all in cis configuration, indicating the potential for separation and recognition of CHBMA isomers. Powder X-ray patterns reveal the structure of TJPU-3Mn sustains after the emission of water molecules obtained by calcining at 150℃ for 2 h.
