چکیده

A novel transition metal polyoxotungstate, [Cu(H2O)6][{Cu(H2O)2}2{Cu(H2O)4H4W12O42}] · 12H2O (1), has been synthesized in aqueous solution and characterized by single-crystal X-ray diffraction, elemental analysis, IR and UV/vis spectroscopy, and TG analysis. The paradodecatungstate anions [H2W12O42]10− are linked by CuO6 octahedra, forming a three-dimensional (3D) structure. The magnetic susceptibility of compound 1 in the temperature range 2 – 300 K shows the presence of antiferromagnetic interactions within the uniform Cu2· · ·Cu3 chains.

From Racemic Units to Polar Materials

A new route is described that enables the design of polar materials using racemic basic building units (BBUs). Λand Δ-[Cu(H2O)(bpy)2] complexes in noncentrosymmetric [Cu(H2O)(bpy)2]2[HfF6]2·3H2O and centrosymmetric [Cu(H2O)(bpy)2][BF4]2 reveal that racemic BBUs in the solid state can lead directly to noncentrosymmetry. The structure is polar if only mirror or glide planes relate the leftand rig...
