Title: Materials Data on SrTcN3 by Materials Project

Abstract

SrTcN3 is Aluminum carbonitride-like structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Sr2+ is bonded in a 6-coordinate geometry to six N3- atoms. There are a spread of Sr–N bond distances ranging from 2.56–2.77 Å. Tc7+ is bonded to five N3- atoms to form distorted TcN5 trigonal bipyramids that share a cornercorner with one NSr2TcN tetrahedra, corners with two equivalent TcN5 trigonal bipyramids, and edges with two equivalent TcN5 trigonal bipyramids. There are a spread of Tc–N bond distances ranging from 1.77–2.06 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded to one Sr2+ and three equivalent Tc7+ atoms to form distorted NSrTc3 tetrahedra that share corners with seven NSrTc3 tetrahedra, corners with four equivalent NSr3Tc trigonal pyramids, edges with two equivalent NSrTc3 tetrahedra, and an edgeedge with one NSr3Tc trigonal pyramid. In the second N3- site, N3- is bonded to two equivalent Sr2+, one Tc7+, and one N3- atom to form distorted NSr2TcN tetrahedra that share corners with seven NSrTc3 tetrahedra, a cornercorner with one TcN5 trigonal bipyramid, corners with five equivalent NSr3Tc trigonal pyramids, and an edgeedge with one NSr3Tc trigonal pyramid. The N–N bond length ismore » 1.28 Å. In the third N3- site, N3- is bonded to three equivalent Sr2+ and one Tc7+ atom to form distorted NSr3Tc trigonal pyramids that share corners with nine NSrTc3 tetrahedra, corners with two equivalent NSr3Tc trigonal pyramids, edges with two NSrTc3 tetrahedra, and edges with two equivalent NSr3Tc trigonal pyramids.« less
