Two new types of coordination cage have been prepared and structurally characterized: [M16(mu-L1)24]X32 are based on a tetra-capped truncated tetrahedral core and have a bridging ligand L1 along each of the 24 edges; [M12(mu-L1)12(mu3-L2)4]X24 are based on a cuboctahedral core which is supported by a combination of face-capping ligands L2 and edge-bridging ligands L1. The difference between the two illustrates how combinations of ligands with different coordination modes can generate coordination cages which are not available using one ligand type on its own.
[M16(μ-L1)24]X32基于一个四帽截角四面体核，并且沿着24条边中的每一条都有一个桥连配体L1；[M12(μ-L1)12(μ3-L2)4]X24基于一个立方八面体核，该核由面帽配体L2和边桥连配体L1的组合支撑。两者之间的差异说明了具有不同配位模式的配体组合如何能够生成仅使用一种配体类型无法得到的配位笼。
