Abstract
Reaction of 1,4-bis(1H-imidazol-1-yl)benzene ligand (bib) and CuSiF6 in water/ dimethylsulfoxide (DMSO) as the solvent mixture affords purple crystals of a metal-organic framework, 1, suitable for single crystal X-ray diffraction (SCXRD) analysis. 1 crystallizes in the triclinic P − 1 space group: a = 12.694(2) Å, b = 13.455(2) Å, c = 13.740(3) Å, α = 88.919(7)°, β = 67.864(7)°, γ = 65.029(6)°, V = 1942.9(6) Å3. 1 was found to be a new phase of SIFSIX-23-Cu. Moreover, in the structure pores a cluster formed by two molecules of DMSO and ten molecules of water was identified possessing a double ice Ih-like shape.File in questo prodotto:
