VMn3Te2(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six PO4 tetrahedra. There is three shorter (1.97 Å) and three longer (1.98 Å) V–O bond length. There are three inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.00 Å) and three longer (2.34 Å) Mn–O bond lengths. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (2.15 Å) and three longer (2.37 Å) Mn–O bond lengths. In the third Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 pentagonal pyramids that share corners with six PO4 tetrahedra. There are three shorter (2.04 Å) and three longer (2.27 Å) Mn–O bond lengths. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one VO6 octahedra, a cornercorner with one MnO6 octahedra, and a cornercorner with one MnO6 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 24–56°. There are a spread of P–O bond distances ranging from 1.49–1.66 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one VO6 octahedra, a cornercorner with one MnO6 octahedra, and a cornercorner with one MnO6 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 34–43°. There are a spread of P–O bond distances ranging from 1.51–1.62 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.00 Å) and three longer (2.70 Å) Te–O bond lengths. In the second Te4+ site, Te4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.08 Å) and three longer (2.40 Å) Te–O bond lengths. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Mn2+, one P5+, and one Te4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Mn2+, one P5+, and one Te4+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one V4+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mn2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one V4+, one P5+, and one Te4+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Mn2+, one P5+, and one Te4+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mn2+ and one P5+ atom.
