Self-assembled hetero-bimetallic coordination cage and cation-clusters with µ2-Cl bridging using a flexible two-arm ferrocene amide linker†‡
Abstract
One flexible, discrete coordination cage [Cu2(3-BPFA)4(H2O)2](ClO4)4·4CH3OH (1), and two cation-clusters with µ2-Cl bridging [Ni2(µ-Cl)(3-BPFA)4(H2O)2](ClO4)3 (2) and [Co2(µ-Cl)(3-BPFA)4(H2O)2](ClO4)4·4CH3OH (3), containing the ferrocenyl functionality were prepared via coordination-driven
