摘要

1,4-双（1h -咪唑-1-酰基）苯配体（bib）和CuSiF6在水/二甲基亚砜（DMSO）中作为溶剂混合物反应得到金属-有机框架的紫色晶体，1，适合单晶x射线衍射（SCXRD）分析。1在三斜晶系的结晶P−1空间群:a = 12.694 (2), b = 13.455 (2) a, c = 13.740(3),α= 88.919(7)°,β= 67.864(7)°,γ= 65.029(6)°,V = 1942.9 (6) A3。发现1是sif6 -23- cu的新相。此外，在结构孔隙中，鉴定出由两个DMSO分子和十个水分子形成的簇具有双冰i -like形状。

Ice Ih Shaped Water Cluster in the Cage of an Ultramicroporous Metal-Organic Framework

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.
