A mesoporous ionic solid with 272 Au Ag Cu complex cations in a super huge crystal lattice.

Here, we report a unique mesoporous ionic solid () generated from a cationic Au Ag Cu dodecanuclear complex with d-penicillamine depending on the homochirality and crystallization conditions. crystallizes in the cubic space group of 432 with an extremely large cell volume of 2 171 340 Å, containing 272 Au Ag Cu complex cations in the unit cell. In , the complex cations are connected to each other through CH⋯π interactions in a zeotype framework, the topology of which is the same as that of the metal-organic framework in MIL-101, with similar but much larger two types of polyhedral pores with internal diameters of 38.
