Li9Mn2Co5O16 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Li9Mn2Co5O16 sheet oriented in the (1, 0, 3) direction. there are five inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 2.00–2.20 Å. In the second Li1+ site, Li1+ is bonded in a 2-coordinate geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.99–2.41 Å. In the third Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.98–2.32 Å. In the fourth Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.90–2.38 Å. In the fifth Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.01 Å) and two longer (2.14 Å) Li–O bond lengths. Mn+4.50+ is bonded in a 2-coordinate geometry to four O2- atoms. There are a spread of Mn–O bond distances ranging from 1.83–2.22 Å. There are three inequivalent Co+2.80+ sites. In the first Co+2.80+ site, Co+2.80+ is bonded in a 2-coordinate geometry to two O2- atoms. There is one shorter (1.86 Å) and one longer (1.94 Å) Co–O bond length. In the second Co+2.80+ site, Co+2.80+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Co–O bond distances ranging from 1.83–2.18 Å.
