| 1,3,5-三(苯基)-4'-三膦酸苯 | 1,3,5-tris(4-phosphonophenyl)benzene | 1045720-71-5 | C24H21O9P3 | 546.347 |
The single-crystal X-ray structure of a microporous alkaline-earth phosphonate incorporating a new triphosphonate ligand is presented. Sr2(H2L)(CH3OH)(H2O)4, where L = 1,3,5-tris(4-phosphonophenyl)benzene, crystallizes in triclinic space group P-1 (a = 6.9230(4) Å, b = 15.3370(9) Å, c = 16.1930(11) Å, α = 62.201(3)°, β = 85.288(4)°, γ = 86.665(4)°). The solid is sustained by cooperative interactions between both one-dimensional inorganic and organic columns and forms a two-fold interpenetrated microporous structure. Gas and vapour sorption experiments confirm the microporosity. Based upon the sustaining interactions, this compound can serve as a model for more porous structures as extension of its structure disfavours further interpenetration.Key words: metal–organic framework, coordination polymer, phosphonate, microporous, alkaline earth.
