N2 - A basic lead carbonate-montmorillonite complex was prepared by treating a natural montmorillonite hydrothermally for 120 h at 250°C with lead powder, dry ice and lead nitrate solution. The product is a non-swelling material showing well-outlined, hexagonal, thin plates <1 μm in size; the symmetry is pseudo-orthorhombic, a = 5.141(7) Å, b = 9.005(5) Å, c = 17.420(4) Å, and Z = 2. The X-ray powder pattern is characterized by a 17.4 Å reflection and an integral series to the 14th order. The crystal structure of the 17 Å-mineral was determined and refined as a 2:1 dioctahedral smectite interlayered with a hydrocerussite-like layer by a one-dimensional Fourier synthesis method. -from Authors
