Fig. 2: The crystal structure and in situ exfoliation process of NNU-55-M.
From: Tandem utilization of CO2 photoreduction products for the carbonylation of aryl iodides
a The coordination environments of three crystallographic independent M atoms (M1/M2/M3). b The three-dimensional framework and metal coordination environment of NNU-55-M (M = Co/Ni). c Schematic diagram of crystal structure to NNU-55-Co is corresponding to b. It shows that no such in situ exfoliation occurs to NNU-55-Co. d The schematic illustration of NNU-55-Ni (Bulk) shows the pillar-layer structure. The red dashed region is equated to b. e NNU-55-Ni (Bulk) experienced an in situ exfoliation process, NNU-55-Ni (Nanosheets) were formed.
