A nanosized porous metal-organic framework assembled with mutually interdigitated two-dimensional coordination motifs

Abstract A metal-organic framework based on silver(I) and mixed ligands {[Ag 2 (ibpa) 2 (bpp) 2 ]·5H 2 O} n ( 1 ) (Hibpa = 4-isobutyl-α-methylphenylacetic acid, bpp = 1,3-di(4-pyridyl)propane) has been synthesized by the solvothermal reaction. Single crystal X-ray diffraction revealed that 1 has a two-dimensional (2D) layer motif, and the layers of 1 are further mutually interdigitated to give rise to a 3D nanosized porous framework in the dimension of 13.23 × 13.19 A. Interestingly, the host framework encapsulates unique hexamer water clusters and is further connected into (H 2 O) 6n tapes by water–water hydrogen bonding interactions. Thermogravimetric analysis (TGA) was conducted to determine the thermal stability of 1 .
