MnO5(B4O10)O is alpha Niobium phosphide structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two (B4O10)O clusters and two MnO5 clusters. In each (B4O10)O cluster, there are four inequivalent B sites. In the first B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.31–1.42 Å. In the second B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.35–1.45 Å. In the third B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.33–1.45 Å. In the fourth B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.32–1.46 Å. There are eleven inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one O atom. The O–O bond length is 1.33 Å. In the second O site, O is bonded in a single-bond geometry to one O atom. The O–O bond length is 1.35 Å. In the third O site, O is bonded in a single-bond geometry to one B atom. In the fourth O site, O is bonded in a distorted bent 150 degrees geometry to two B atoms. In the fifth O site, O is bonded in a bent 150 degrees geometry to two B atoms. In the sixth O site, O is bonded in a single-bond geometry to one B and one O atom. In the seventh O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the eighth O site, O is bonded in a single-bond geometry to one O atom. The O–O bond length is 1.33 Å. In the ninth O site, O is bonded in a bent 150 degrees geometry to two B atoms. In the tenth O site, O is bonded in a distorted single-bond geometry to one B and one O atom. In the eleventh O site, O is bonded in a distorted single-bond geometry to one B and one O atom. In each MnO5 cluster, Mn is bonded in a distorted tetrahedral geometry to four O atoms. There are a spread of Mn–O bond distances ranging from 1.59–1.80 Å. There are five inequivalent O sites. In the first O site, O is bonded in a water-like geometry to two O atoms. Both O–O bond lengths are 1.46 Å. In the second O site, O is bonded in a distorted single-bond geometry to one Mn and one O atom. In the third O site, O is bonded in a distorted single-bond geometry to one Mn and one O atom. In the fourth O site, O is bonded in a single-bond geometry to one Mn atom. In the fifth O site, O is bonded in a single-bond geometry to one Mn atom.
