Abstract

Mn(B2O7)2O2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two water water molecules and two Mn(B2O7)2 clusters. In each Mn(B2O7)2 cluster, Mn is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Mn–O bond distances ranging from 1.59–2.04 Å. 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 1.36–1.39 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 1.37–1.39 Å. In the third B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.45–1.50 Å. In the fourth B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.45–1.49 Å. There are fourteen inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Mn atom. In the second O site, O is bonded in a 2-coordinate geometry to one Mn and one O atom. The O–O bond length is 1.31 Å. In the third O site, O is bonded in a single-bond geometry to one Mn atom. In the fourth O site, O is bonded in a single-bond geometry to one O atom. The O–O bond length is 2.01 Å. In the fifth O site, O is bonded in a single-bond geometry to one B atom. In the sixth O site, O is bonded in a bent 120 degrees geometry to two B atoms. 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 B atom. In the ninth O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the tenth O site, O is bonded in a distorted bent 150 degrees geometry to one Mn and one B atom. In the eleventh O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the twelfth O site, O is bonded in a single-bond geometry to one B atom. In the thirteenth O site, O is bonded in a bent 120 degrees geometry to two B and one O atom. In the fourteenth O site, O is bonded in a 1-coordinate geometry to one Mn and one O atom.
