Half-sandwich M6(L1)4 octahedral and M8(L2)4 cubic cages have been assembled by flexible Schiff-base ligands upon coordination to Cp*Rh(iii) organometallic acceptors. In particular, the Rh(iii)-based half-sandwich M2(HL1)2 macrocycle rearranges in solution to give a M6(L1)4 cage.
灵活的希夫碱配体与 Cp*Rh(iii) 有机金属受体配位后,形成了半三明治 M6(L1)4 八面体笼和 M8(L2)4 立方笼。其中,基于 Rh(iii) 的半三明治 M2(HL1)2 大环在溶液中重新排列,形成 M6(L1)4 笼。
