Sn Sb Sb P
SnSb2P crystallizes in the trigonal R3m space group. Sn(1) is bonded to one Sb(1) and three equivalent Sb(2) atoms to form distorted SnSb4 trigonal pyramids that share  a cornercorner with one Sb(2)Sn3SbP trigonal bipyramid, corners with three equivalent Sb(1)SnSbP3 trigonal bipyramids, corners with six equivalent Sn(1)Sb4 trigonal pyramids, and edges with three equivalent P(1)Sb4 trigonal pyramids. The Sn(1)-Sb(1) bond length is 2.26 Å. All Sn(1)-Sb(2) bond lengths are 2.99 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one Sn(1), one Sb(2), and three equivalent P(1) atoms to form distorted SbSnSbP3 trigonal bipyramids that share corners with six equivalent Sb(1)SnSbP3 trigonal bipyramids,  a cornercorner with one P(1)Sb4 trigonal pyramid, corners with three equivalent Sn(1)Sb4 trigonal pyramids, and edges with three equivalent Sb(2)Sn3SbP trigonal bipyramids. The Sb(1)-Sb(2) bond length is 2.26 Å. All Sb(1)-P(1) bond lengths are 2.99 Å. In the second Sb site, Sb(2) is bonded to three equivalent Sn(1), one Sb(1), and one P(1) atom to form distorted SbSn3SbP trigonal bipyramids that share corners with six equivalent Sb(2)Sn3SbP trigonal bipyramids,  a cornercorner with one Sn(1)Sb4 trigonal pyramid, corners with three equivalent P(1)Sb4 trigonal pyramids, and edges with three equivalent Sb(1)SnSbP3 trigonal bipyramids. The Sb(2)-P(1) bond length is 2.26 Å. P(1) is bonded to one Sb(2) and three equivalent Sb(1) atoms to form distorted PSb4 trigonal pyramids that share  a cornercorner with one Sb(1)SnSbP3 trigonal bipyramid, corners with three equivalent Sb(2)Sn3SbP trigonal bipyramids, corners with six equivalent P(1)Sb4 trigonal pyramids, and edges with three equivalent Sn(1)Sb4 trigonal pyramids.
