Abstract

Na2MnFeCd(PO4)3 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are two shorter (2.36 Å) and four longer (2.49 Å) Na–O bond lengths. In the second Na1+ site, Na1+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.24–2.86 Å. In the third Na1+ site, Na1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Na–O bond distances ranging from 2.31–2.92 Å. Mn2+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with two PO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 2.10–2.45 Å. Fe3+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Fe–O bond distances ranging from 1.91–2.48 Å. There are two inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.48 Å) and two longer (2.66 Å) Cd–O bond lengths. In the second Cd2+ site, Cd2+more » is bonded in a distorted linear geometry to two equivalent O2- atoms. Both Cd–O bond lengths are 2.10 Å. There are four inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of P–O bond distances ranging from 1.48–1.51 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 43°. There is two shorter (1.55 Å) and two longer (1.57 Å) P–O bond length. In the third P5+ site, P5+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of P–O bond distances ranging from 1.53–1.69 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There is two shorter (1.51 Å) and two longer (1.62 Å) P–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Mn2+, and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Fe3+, and one P5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Na1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one Mn2+, and one O2- atom. The O–O bond length is 1.44 Å. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, one Mn2+, one Cd2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, one Mn2+, one Cd2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one Fe3+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 4-coordinate geometry to two Na1+, one Mn2+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the tenth O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, two equivalent Fe3+, and one O2- atom. In the eleventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Na1+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a trigonal planar geometry to one Mn2+, one Fe3+, and one Cd2+ atom.« less
