Abstract

A new bimetallic selenite compound, Cd(VO₂)₄(SeO₃)₃·H ₂O, with vanadium and cadmium metals was synthesized from hydrothermal reactions of V₂O₅, Cd(NO₃)₂·2H₂O, and SeO₂ in water at 230°C. This compound crystallizes in a triclinic unit cell with the space group P1 (No. 2) and the lattice parameters a = 6.2999(4) Å, b = 7.4078(4) Å, c = 15.7525(9) Å, = 100.881(1)°, β = 98.796(1)°, γ = 93.690(1)°, V= 710.14(7) Å³, Z = 2. The crystal structure was determined by X-ray single-crystal diffraction techniques and was refined with R = 0.0336 and wR₂ = 0.0819 for all 3175 reflection data. The structure can be described as layers with pillars between the layers. The layer is composed of dimers of VO₅ square pyramids and dimmers of CdO₇ decahedra connected to one another by sharing corner and/or edge oxygen atoms, and the pillars are composed of VO₆ distorted octahedra connected to one another with capping SeO₃^2- selenite groups. The coordination number of Cd atom in the structure shows a rare example of hepta-coordination with only oxygen donor atoms
