Materials Data on Na5SrTaP4 by Materials Project
Abstract
Na5SrTaP4 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are five inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to five P3- atoms to form distorted NaP5 square pyramids that share corners with three equivalent NaP5 square pyramids, a cornercorner with one TaP4 tetrahedra, corners with seven NaP4 trigonal pyramids, edges with three NaP5 square pyramids, edges with two equivalent TaP4 tetrahedra, and edges with four NaP4 trigonal pyramids. There are a spread of Na–P bond distances ranging from 3.06–3.31 Å. In the second Na1+ site, Na1+ is bonded to five P3- atoms to form distorted NaP5 square pyramids that share corners with five NaP5 square pyramids, a cornercorner with one TaP4 tetrahedra, corners with seven NaP4 trigonal pyramids, an edgeedge with one NaP5 square pyramid, edges with two equivalent TaP4 tetrahedra, and edges with four NaP4 trigonal pyramids. There are a spread of Na–P bond distances ranging from 3.03–3.28 Å. In the third Na1+ site, Na1+ is bonded to four P3- atoms to form distorted NaP4 trigonal pyramids that share corners with six NaP5 square pyramids, corners with two equivalent TaP4 tetrahedra, corners with eight NaP4 trigonal pyramids, edges with two equivalentmore »
