Synthesis and Structure Evolution in Metal Carbazole Diphosphonates Followed by Electron Diffraction.

ABSTRACT: To access porous metal phosphonates, a new V-shaped, rigid, and sterically demanding diphosphonic acid, namely 3,6-diphosphono-9H-carbazole (H₄L), was designed and employed in a high-throughput investigation. Screening of different metal salts and subsequent optimization studies resulted in the isolation of two porous metal phosphonates [Cu₂(H₂O)₂(L)]·2H₂O (CAU-37) and [Zn_6.75(H₂O)_1.5(HL)_2.5(L)_1.5]·8H₂O (CAU-57). Structure determination was accomplished by electron diffraction and the dehydration behavior of CAU-37 was followed in situ. A rare case of intralayer water de-/adsorption in CAU-37 was found which leads to a cell volume chang
