Materials Data on Na3Sr3AlP4 by Materials Project
Na3Sr3AlP4 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Na1+ is bonded to four P3- atoms to form distorted NaP4 trigonal pyramids that share corners with two equivalent AlP4 tetrahedra, corners with eight equivalent NaP4 trigonal pyramids, and an edgeedge with one AlP4 tetrahedra. There are a spread of Na–P bond distances ranging from 2.91–3.24 Å. Sr2+ is bonded in a 6-coordinate geometry to six P3- atoms. There are a spread of Sr–P bond distances ranging from 3.11–3.49 Å. Al3+ is bonded to four P3- atoms to form AlP4 tetrahedra that share corners with six equivalent NaP4 trigonal pyramids and edges with three equivalent NaP4 trigonal pyramids. There are three shorter (2.42 Å) and one longer (2.49 Å) Al–P bond lengths. There are two inequivalent P3- sites. In the first P3- site, P3- is bonded in a 1-coordinate geometry to three equivalent Na1+, six equivalent Sr2+, and one Al3+ atom. In the second P3- site, P3- is bonded in a 8-coordinate geometry to three equivalent Na1+, four equivalent Sr2+, and one Al3+ atom.
