title: Layered lanthanide molybdate pillared by chiral [lambda-Mo2O4EDTA]2-.
abstract: Hydrothermal reactions of Na2[Mo2O4EDTA].5H2O and LnCl3.6H2O produce the chiral layered lanthanide molybdate oxides pillared by the chiral cluster ligand, [Ln(H2O)MoO4]2[lambda-Mo2O4EDTA] (Ln = Gd, 1; Eu, 2; Tb, 3; Y, 4). The tetradentate molybdate bridges Ln3+ to form a square grid structure, which is pillared by the chiral cluster ligand, [lambda-Mo2O4EDTA]2-, into a 3-D chiral framework structure. Strong VCD (vibrational circular dichroism) signals confirm the chirality of the bulk oxide materials. These bimetallic oxide materials are of highly thermal stability. The magnetic interactions between the Ln3+ ions in 1 and 3 are weak antiferromagnetic.
