Single crystals of CdCu₁.₅Mg₁.₅Pb₀.₅V₃O₁₂ have been prepared in closed steel tubes using V₂O₅ as a flux. The orange crystals show monoclinic symmetry, space group C⁶₂ₕ-C2/c, a = 12.417(5), b = 12.983(6), c = 6.911(3) Å , β = 113.02(1)°, Z = 4. CdCu₁.₅Mg₁.₅Pb₀.₅V₃O₁₂ reveals a relationship to the Johillerite type, but it is characterized by an additional point position for cadmium, situated between the square planar CuO₄ polygons of the Johillerite structure.
