Two polyoxometalate-based silver(I) compounds including a three-dimensional porous crystalline array and a double-helicate bisupporting cluster were achieved using metal-organic helicates and Keggin [PMo(12)O(40)](3-) as secondary building blocks.

A series of 3D homochiral manganese-lanthanide frameworks have been synthesized based on chiral camphoric acid. In the heterometallic features, D-camphoric acids are unprecedentedly embedded in three coordination modes.
