Materials Data on K3P3O10 by Materials Project
K3P3O10 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent K sites. In the first K site, K is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of K–O bond distances ranging from 2.68–3.07 Å. In the second K site, K is bonded in a 5-coordinate geometry to six O atoms. There are a spread of K–O bond distances ranging from 2.62–3.21 Å. In the third K site, K is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of K–O bond distances ranging from 2.71–3.34 Å. There are three inequivalent P sites. In the first P site, P is bonded in a bent 120 degrees geometry to two O atoms. Both P–O bond lengths are 1.51 Å. In the second P site, P is bonded in a bent 120 degrees geometry to two O atoms. There is one shorter (1.50 Å) and one longer (1.51 Å) P–O bond length. In the third P site, P is bonded in a bent 120 degrees geometry to two O atoms. Both P–O bond lengths are 1.50 Å. There are ten inequivalent O sites. In the first O site, O is bonded in a distorted T-shaped geometry to two K and one O atom. The O–O bond length is 1.33 Å. In the second O site, O is bonded in a distorted single-bond geometry to one K and one P atom. In the third O site, O is bonded in a distorted single-bond geometry to three K and one P atom. In the fourth O site, O is bonded in a distorted single-bond geometry to two K and one P atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to two K atoms. In the sixth O site, O is bonded in a distorted single-bond geometry to three K and one P atom. In the seventh O site, O is bonded in a distorted trigonal planar geometry to one K and two O atoms. The O–O bond length is 1.34 Å. In the eighth O site, O is bonded in a distorted single-bond geometry to two K and one P atom. In the ninth O site, O is bonded in a distorted T-shaped geometry to two K and one O atom. In the tenth O site, O is bonded in a distorted trigonal planar geometry to two K and one P atom.
