KEu(PO3)4 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.82–3.24 Å. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.41–2.56 Å. There are four inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.51–1.62 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.63 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.61 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Eu3+, and one P5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Eu3+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Eu3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Eu3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Eu3+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Eu3+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Eu3+, and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Eu3+, and one P5+ atom.
