A metal-organic framework based on silver(I) and mixed ligands {[Ag2(ibpa)2(bpp)2]·5H2O}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 13.23×13.19Å. Interestingly, the host framework encapsulates unique hexamer water clusters and is further connected into (H2O)6n tapes by water–water hydrogen bonding interactions. Thermogravimetric analysis (TGA) was conducted to determine the thermal stability of 1. A nanosized porous metal-organic framework constructed with an interesting flexible 2D interdigitated layer and encapsulating unique (H2O)6n tapes based on hexamer water clusters. [Display omitted] ► Firstly, a nanosized porous metal-organic framework has been synthesized. ► Secondly, it is comprised of the mutually interdigitated 2D layer motifs. ► Thirdly, it encapsulates unique hexamer–water clusters. ► Fourthly, the water clusters are connected into (H2O)6n tapes by hydrogen bonds.
