以MoO3,H3PO4和2,2′-联吡啶胺(DPA)等为原料,经过水热处理,再利用N,N-二甲基甲酰胺(DMF)溶剂重结晶制备了多金属氧酸盐基超分子化合物(HDPA.DMF)2(HDPA.2DMF)(PMo12O40),并对其进行了元素分析I、R表征和X-射线单晶结构解析.晶体学参数:三斜晶系,P-1空间群,a=1.2493(3)nm,b=1.2694(3)nm,c=1.3002(2)nm,α=94.647(17)°,β=97.136(16)°,γ=111.909(18)°,V=1.8799(6)nm3.对其X-射线单晶结构分析结果表明,α-Keggin型PMo12O430-阴离子、质子化了的DPA和溶剂DMF分子形成了一个由氢键、静电引力、π-π作用、范德华力等多种作用力协同作用的复杂超分子体系.
A series of polyoxometalate-based polyoxometalates were prepared by recrystallization from MoO3, H3PO4 and DPA and other hydrothermal compounds and N, N-dimethylformamide (DMF) (HDPA.DMF) 2 (HDPA.2DMF) (PMo12O40), and its elemental analysis I, R characterization and X-ray single crystal structure analysis. Crystallographic parameters: triclinic, P-1 space Α = 94.647 (17) °, β = 97.136 (16) °, γ = 111.909 (18) °, a = 1.2493 (3) nm, b = V = 1.8799 (6) nm 3. The results of X-ray single crystal structure analysis show that the α-Keggin-type PMo12O430- anion, the protonated DPA and the solvent DMF form a hydrogen bond, electrostatic attraction, π-π Role, van der Waals force and other forces synergy of complex supramolecular system.
