This structure is layered: the B12 icosahedra and bridging carbons variety a community plane that spreads parallel to the c-plane and stacks together the c-axis. The lattice has two simple composition units �?the B12 icosahedron plus the B6 octahedron. Due to modest size on the B6 octahedra, they cannot interconnect. https://dip-pipe-for-glass-lined04714.dbblog.net/5092731/the-ultimate-guide-to-nano-ferric-oxide
