✦ Synopsis

Ionothermal reaction between Ni 2+ and 1,3,5-benzentricarboxylic acid (H 3 BTC) with [AMI]Cl (AMI ¼ 1-amyl-3-methylimidazolium) as the reaction medium produced a novel 3D mixed-ligand metalorganic framework

The framework is formed by connecting 2D planes, made up of 32-and 48-membered rings, through 1D chains composed of 32-membered rings. The two BTC 3À ligands in 1 show the same connectivity mode with two bidentate and one m 2 bridging carboxylic groups. This is a new connectivity mode to the already existing 17 in the Ni-BTC system. The role of MI and [AMI]Cl in the structure formation is discussed.
