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

Ionothermal reaction of isophthalate (H2ip), and colbolt(II) nitrate under 1-ethly-3-methylimidazolium bromide (EMimBr) as solvent leads to a novel three dimensional metal–organic framework (EMim)2[Co3(ip)4] (1). It can be described as an eight-connected CsCl-type net (42464) 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.

Ionothermal reaction of isophthalate and Co(II) leads to the generation of a three dimensional complex, (EMim)2[Co3(ip)4].
