Abstract

CN3Sn4(PO4)3 crystallizes in the tetragonal P4_3 space group. The structure is three-dimensional and consists of four guanidine molecules and one Sn4(PO4)3 framework. In the Sn4(PO4)3 framework, there are four inequivalent Sn+3.50+ sites. In the first Sn+3.50+ site, Sn+3.50+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Sn–O bond distances ranging from 2.10–2.13 Å. In the second Sn+3.50+ site, Sn+3.50+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Sn–O bond distances ranging from 2.09–2.12 Å. In the third Sn+3.50+ site, Sn+3.50+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Sn–O bond distances ranging from 2.06–2.11 Å. In the fourth Sn+3.50+ site, Sn+3.50+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are one shorter (2.08 Å) and two longer (2.12 Å) Sn–O bond lengths. 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 1.54–1.56 Å. In the second P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.55 Å) and two longer (1.56 Å) P–O bond length. 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 1.54–1.57 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Sn+3.50+ and one P5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Sn+3.50+ and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Sn+3.50+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Sn+3.50+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn+3.50+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn+3.50+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn+3.50+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sn+3.50+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sn+3.50+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn+3.50+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn+3.50+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sn+3.50+ and one P5+ atom.
