The crystal structure described by Ag3SnP7 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to one Sn(1), one P(4), and two equivalent P(2) atoms. In the second Ag site, Ag(2) is bonded in a distorted trigonal non-coplanar geometry to one Sn(1), one P(1), one P(2), and one P(3) atom. Sn(1) is bonded in a 6-coordinate geometry to one Ag(1), two equivalent Ag(2), one P(4), and two equivalent P(3) atoms. There are four inequivalent P sites. In the first P site, P(1) is bonded to one Ag(2), one P(2), one P(3), and one P(4) atom to form PAgP3 tetrahedra that share  a cornercorner with one P(1)AgP3 tetrahedra, corners with two equivalent P(2)Ag2P2 tetrahedra, and corners with two equivalent P(3)AgSnP2 tetrahedra. In the second P site, P(2) is bonded to one Ag(1), one Ag(2), one P(1), and one P(3) atom to form PAg2P2 tetrahedra that share  a cornercorner with one P(2)Ag2P2 tetrahedra, corners with two equivalent P(1)AgP3 tetrahedra, corners with two equivalent P(3)AgSnP2 tetrahedra, and corners with two equivalent P(4)AgSnP2 tetrahedra. In the third P site, P(3) is bonded to one Ag(2), one Sn(1), one P(1), and one P(2) atom to form PAgSnP2 tetrahedra that share  a cornercorner with one P(3)AgSnP2 tetrahedra, corners with two equivalent P(2)Ag2P2 tetrahedra, corners with two equivalent P(1)AgP3 tetrahedra, and corners with two equivalent P(4)AgSnP2 tetrahedra. In the fourth P site, P(4) is bonded to one Ag(1), one Sn(1), and two equivalent P(1) atoms to form distorted PAgSnP2 tetrahedra that share corners with four equivalent P(2)Ag2P2 tetrahedra and corners with four equivalent P(3)AgSnP2 tetrahedra. is represented by the CIF file [CIF]
