Cubic and chain-like structure of {alpha}-Mn{sub 2}O{sub 3} with a high surface area was prepared by air oxidation of manganese chloride through sol process by adding hexamine and mercaptosuccinic acid as wetting agent, respectively. The as-synthesized products were characterized with X-ray powder diffraction (XRD), Energy Dispersive X-ray spectroscopy (EDX), transmission electron microscope (TEM), and selected area electron diffraction (SAED). The possible formation mechanism of {alpha}-Mn{sub 2}O{sub 3} cubic and chain-like nanostructures has been proposed and discussed. -- Graphical abstract: Cubic and chain-like nanostructure of {alpha}-Mn{sub 2}O{sub 3} has been synthesized by air oxidation of manganese chloride as precursor, hexamine, and mercaptosuccinic acid as wetting agent, respectively. Display Omitted Research highlights: {yields} Cubic nanostructure of {alpha}-Mn{sub 2}O{sub 3} is obtained using hexamine as surfactant. {yields} Chain-like structure of {alpha}-Mn{sub 2}O{sub 3} is obtained using mercaptosuccinic acid as surfactant. {yields} The linking nature of mercaptosuccinic acid is proved. {yields} Mercaptosuccinic acid accelerates the growth of material.
