729: 516:. It is, however, rarely the case in natural materials. In addition to being chemically complex, natural birnessite crystals are structurally disordered with respect to the layer stacking and the flatness of the layers. A natural birnessite crystal may contain only a few layers, and they are often bent and always imperfectly stacked with orientational and translational loss of registry. The stacking disorder is referred to as "turbostratic" when the layers are oriented completely at random. Natural birnessite with turbostratically stacked layers is named vernadite, and the synthetic analog is named δ-MnO 675: 687: 710: 652: 3253: 575:(r = 0.74 Å) sorbed on a vacancy is transformed into a smaller tetrahedral complex (r = 0.58 Å) to penetrate into the octahedral Mn vacancy, and is subsequently converted to the low-spin state before being oxidized to Co by Mn, which is reduced to Mn. The surface-catalyzed, redox-driven uptake of Co leads also to a billion-fold enrichment in marine ferromanganese deposits compared to Co between ferromanganese deposits and Pb. 29: 556:). The relative stability of the interlayer cations has been evaluated experimentally and theoretically by surface complexation modeling and computational chemistry. Pb has the highest stability at the HBi surface, and the high geochemical affinity of Pb for birnessite probably explains its billion-fold enrichment in marine ferromanganese deposits compared to 358:
