Abstract

NaTh2(PO4)3 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Na1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Na–O bond distances ranging from 2.35–2.55 Å. There are two inequivalent Th4+ sites. In the first Th4+ site, Th4+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Th–O bond distances ranging from 2.31–2.61 Å. In the second Th4+ site, Th4+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Th–O bond distances ranging from 2.36–2.67 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. In the second P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.55–1.57 Å. In the third P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two Th4+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Th4+ and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Th4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Th4+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Th4+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Na1+, one Th4+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Th4+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two Th4+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, one Th4+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Th4+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Th4+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a 1-coordinate geometry to one Th4+ and one P5+ atom.
