Sr Nb W
SrNbW crystallizes in the trigonal R3m space group. Sr(1) is bonded to four equivalent Nb(1) and four equivalent W(1) atoms to form distorted SrNb4W4 hexagonal bipyramids that share corners with four equivalent Nb(1)Sr4W4 hexagonal bipyramids, corners with four equivalent W(1)Sr4Nb4 hexagonal bipyramids, edges with six equivalent Nb(1)Sr4W4 hexagonal bipyramids, edges with six equivalent W(1)Sr4Nb4 hexagonal bipyramids, and edges with twelve equivalent Sr(1)Nb4W4 hexagonal bipyramids. There are three shorter (2.72 Å) and one longer (3.88 Å) Sr(1)-Nb(1) bond length. There are three shorter (2.72 Å) and one longer (3.84 Å) Sr(1)-W(1) bond length. Nb(1) is bonded to four equivalent Sr(1) and four equivalent W(1) atoms to form distorted NbSr4W4 hexagonal bipyramids that share corners with four equivalent Sr(1)Nb4W4 hexagonal bipyramids, corners with four equivalent W(1)Sr4Nb4 hexagonal bipyramids, edges with six equivalent Sr(1)Nb4W4 hexagonal bipyramids, edges with six equivalent W(1)Sr4Nb4 hexagonal bipyramids, and edges with twelve equivalent Nb(1)Sr4W4 hexagonal bipyramids.
