The compound crystallizes in the monoclinic system and belongs to space group P2 1/c with a =1.787 6(4) nm, b =1.179 7(2) nm, c =1.884 8(4) nm, β =116.35(3)°, V = 3.561 9(12) nm 3, Z =4, D c=7.413 Mg/m 3, M r=871.43, μ =5.081 mm -1 , F (000)=8 082, R = 0.045 6 , wR =0.106 3.

The compound crystallizes in the monoclinic system and belongs to space group P2 1/n with a= 1.637 2(3) nm, b=1.481 4(3) nm, c=1.838 4(4) nm, β=113.70(3)°, V=4.082 5(14) nm 3, Z=4, D c=1.508 Mg/m 3, M r=958.85, μ=1.001 mm -1, F(000)=1 920. R 1=0.098 5, wR 2= 0.218 3. Its structure reveals that Mn(Ⅱ) centers and the carboxylate groups of BTC construct 1D O—C—O—Mn chains. Then, adjacent chains are interlinked by benzene rings of BTC to form a novel 3D architecture. It contains eight-membered rings channels that are about 0.8 nm×0.8 nm viewed along the (101) direction. In addition, it is believed that the bpy acts as both an organic ligand and a structure-directing agent in the synthesis of the title compound.展开更多

After intercala- tion of n-butyl amine, the 31P chemical shift of HPO42- group at - 8.0￣- 10.0 ppm moved to 6.0 ppm with a change of 14.0￣16.0 ppm and that of [O3PCH2N(CH2CO2H)2]2- group at - 29.1 ppm changed only 0.5 ppm. Due to the pil- lared effect of [O3PCH2N(CH2CO2H)2]2- groups on the interlayer spacing, intercalated amines such as n-butylamine, n-hexyl amine and n-octyl amine easily reacted with HPO42- group in ZPPMIDA (x=0.66) rather than that in α- ZrP, and carboxylic group (-CO2H) in ZPPMIDA (x=0.66).展开更多
