K5B19O31 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.72–3.00 Å. In the second K1+ site, K1+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.71–3.32 Å. In the third K1+ site, K1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.83 Å) and two longer (2.86 Å) K–O bond lengths. There are ten inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.36–1.41 Å. In the second B3+ site, B3+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of B–O bond distances ranging from 1.47–1.51 Å. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.36 Å) and two longer (1.39 Å) B–O bond length.
