by an in situ generated oxalate group. In HMPP-U3, a one-dimensional structure comprising such dimeric uranyl entities and HMPP ligands is pillared by dib, forming a layered assembly. HMPP-U4 incorporates the dimeric uranyl units connected by HMPP ligands, leading to a two-dimensional arrangement with bpi as the template. HMPP-U5 features a one-dimensional structure composed of the uranyl dimers and
在咪唑衍生物即UO 2(L)2(HMPP-U1),(UO 2)2(L)4的咪唑衍生物存在下,使用羟甲基苯基次膦酸(HMPPA,HL)水热合成了一系列新的铀有机次膦酸盐(dib)(HMPP-U2),(UO 2)2(L)2(ox)(dib)(HMPP-U3),(Hbpi)2 [(UO 2)4(L)6(ox)2 ](HMPP-U4)和(UO 2)2(L)2(ox)(bpbi)2( HMPP-U5)(ox =草酸盐,dib = 1,4-二(1 H-咪唑-1-基)苯,bpi = 1-(联苯基-4-基)-1 H-咪唑,bpbi = 1 -([[1,1'-联苯] -4-基)-1 H-苯并[ d ]咪唑)。HMPP-U1是通过HMPPA与UO 2 2+之间的水热反应直接合成的,具有由HMPP配体桥接的唯一UO 6四方双锥体构成的单链结构。随着咪唑衍生物的进一步引入, HMPP-U2的层状结构形成二齿分子,
