A new eight-connected CsCl-type topological net based on trinuclear Co(II) clusters as nodes

Abstract Ionothermal reaction of isophthalate (H 2 ip), and colbolt(II) nitrate under 1-ethly-3-methylimidazolium bromide (EMimBr) as solvent leads to a novel three dimensional metal–organic framework (EMim) 2 [Co 3 (ip) 4 ] ( 1 ). It can be described as an eight-connected CsCl-type net (4 24 6 4 ) utilizing trinuclear Co(II) clusters as eight-connected nodes and ip ligands as linkers. The imidazolium cation [EMim] + of the ionic liquid acting as charge-compensating agents has interactions with the framework. The magnetic properties studies show ferrimagnetic behavior for 1 .
