(NH4)4[ZnMo6O18(C4H8NO3)(OH)3]·4H2O (1), (NH4)4[CuMo6O18(C4H8NO3)(OH)3]·4H2O (2), (TBA)3(NH4)[ZnMo6O17(C5H9O3)2(OH)]·10H2O (3) (TBA = n-C16H36N), and (NH4)4[CuMo6O18(C5H9O3)2]·16H2O (4), were synthesized by a microwave-assisted method. Single-crystal X-ray diffraction revealed that 1 and 2 contained a tris (trihydroxyl organic compounds) ligand grafted on one side, while two tris ligands were grafted on two sides to
四个新的tris-Anderson多金属氧酸盐(POMs)(NH 4)4 [ZnMo 6 O 18(C 4 H 8 NO 3)(OH)3 ]·4H 2 O(1),(NH 4)4 [CuMo 6 O 18(C 4 H 8 NO 3)(OH)3 ]·4H 2 O(2),(TBA)3(NH 4)[ZnMo 6 O 17(C 5 H 9 O 3)2(OH)]·10H 2 O(3)(TBA = n -C 16 H 36 N)和(NH 4)4 [CuMo 6 O 18(C 5 H 9 O 3)2 ]·16H 2 O (4)是通过微波辅助法合成的。X射线单晶衍射表明,1和2的一侧接有一个tris(三羟基有机化合物)配体,而两侧的两个tris配体接枝了,在3和3中形成χ/δ和δ/δ异构体。分别为4。首次获得χ/δ异构体3的1 H和13 C NMR光谱,其中6个亚甲基在1 H NMR光谱中显示6个峰,在13
