Formation of Gd coordination polymer with 1D chains mediated by Bronsted acidic ionic liquids

Coordination polymer Gd[(SO4)(NO3)(C2H6SO)2] was obtained mediated by Bronsted acid Ionic Liquid, which presents a 1-D chains collected by SO42- groups. Magnetic susceptibility of the polymer reveals weak antiferromagnetic interactions between the Gd(III) ions with the relatively large magneto-caloric effect of -ΔSm=28.8 J Kg−1 K−1 for ΔH= 7T.193
