The compound described by TlP3 crystallizes in the trigonal R3m space group. Tl(1) is bonded to one P(2) and three equivalent P(3) atoms to form TlP4 tetrahedra that share corners with six equivalent Tl(1)P4 tetrahedra and corners with six equivalent P(1)P4 trigonal pyramids. There are three inequivalent P sites. In the first P site, P(1) is bonded to one P(3) and three equivalent P(2) atoms to form PP4 trigonal pyramids that share corners with six equivalent Tl(1)P4 tetrahedra and corners with six equivalent P(1)P4 trigonal pyramids. In the second P site, P(2) is bonded to one Tl(1) and three equivalent P(1) atoms to form distorted PTlP3 trigonal pyramids that share corners with six equivalent P(3)Tl3P tetrahedra and corners with six equivalent P(2)TlP3 trigonal pyramids. In the third P site, P(3) is bonded to three equivalent Tl(1) and one P(1) atom to form PTl3P tetrahedra that share corners with six equivalent P(3)Tl3P tetrahedra and corners with six equivalent P(2)TlP3 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
