Abstract

original image

The modular compound [Mn3+xO7][Bi4O4.5−y] contains a rare example of true 2D maple-leaf lattice of edge-sharing Mn3+/4+ (see picture). This compound displays a magnetic transition at 210 K without evidence for a Néel ordering, which indicates in-plane 2D antiferromagnetism.
