N2 - Six novel 3D layer-pillared lanthanide-transition metal coordination polymers, LnCuX(IN)2(Ac)(H2O) (Ln = Tb, X = Br (1); Ln = Er, X = Cl (2)), [LnCuCl(IN)2(Ac)]•H2O (Ln = Gd (3); Ln = Eu (4)), and [LnCu2Br2(IN)2(Ac)(H 2O)]•nH2O (Ln = Dy, n =0 (5); Ln = Gd, n = 0.5 (6)) (IN = isonicotinate, Ac = acetate), have been obtained by linking Ln-organic layers and diverse Cu-complex pillars under hydrothermal conditions. 1 and 2 are isostructural and formed by 2D Ln-IN-Ac layers and CuX(IN)2 pillars (X = Br (1), X= Cl (2)); 3 and 4 are isomorphic and comprised of 2D Ln-IN-Ac layers and dimeric Cu2Cl(IN)4 pillars; while 5 and 6 are isostructural and built from 2D Ln-IN-Ac layers and tetrameric Cu 4Br4(IN)4 pillars. The magnetic susceptibility investigation of 3 and 6 shows the presence of weak antiferromagnetic exchange interactions between the Ln3+ ions. Compounds 1-6 represent good examples of using 2D Ln-organic layers and diverse Cu-complex pillars as building units to construct intriguing 3D Ln-TM-organic frameworks.
