The material structure described by Tc3P crystallizes in the tetragonal I-4 space group. There are three inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 4-coordinate geometry to four equivalent P(1) atoms. In the second Tc site, Tc(3) is bonded in a distorted water-like geometry to two equivalent P(1) atoms. In the third Tc site, Tc(2) is bonded in a distorted bent 120 degrees geometry to two equivalent P(1) atoms. P(1) is bonded in a 8-coordinate geometry to two equivalent Tc(2), two equivalent Tc(3), and four equivalent Tc(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
