Title: A new 3D nickel(II) framework composed of large rings: Ionothermal synthesis and crystal structure

Ionothermal reaction between Ni{sup 2+} and 1,3,5-benzentricarboxylic acid (H{sub 3}BTC) with [AMI]Cl (AMI=1-amyl-3-methylimidazolium) as the reaction medium produced a novel 3D mixed-ligand metal-organic framework [AMI][Ni{sub 3}(BTC){sub 2}(OAc)(MI){sub 3}] (1) (MI=1-methylimidazole) with [AMI]{sup +} incorporated in the 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{sup 3-} ligands in 1 show the same connectivity mode with two bidentate and one {mu}{sub 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. - Graphical Abstract: A novel 3D framework [AMI][Ni{sub 3}(BTC){sub 2}(OAc)(MI){sub 3}] is obtained in ionothermal system with [AMI]{sup +} incorporating in the cavities as structure directing template and BTC{sup 3-} showing a new coordination fashion. The 3D framework is constructed by 2D layers linked with 1D double chains. The title compound has the middle thermal stability at ca. 280 deg. C.
