The crystal structure described by Ta2P crystallizes in the orthorhombic Pnnm space group. There are six inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a distorted T-shaped geometry to one P(1), one P(2), and one P(3) atom. In the second Ta site, Ta(2) is bonded to one P(1), two equivalent P(2), and two equivalent P(3) atoms to form distorted edge-sharing TaP5 trigonal bipyramids. In the third Ta site, Ta(3) is bonded in a 4-coordinate geometry to one P(1), one P(2), and two equivalent P(3) atoms. In the fourth Ta site, Ta(4) is bonded in a 3-coordinate geometry to one P(3) and two equivalent P(2) atoms. In the fifth Ta site, Ta(5) is bonded in a 4-coordinate geometry to one P(2), two equivalent P(1), and two equivalent P(3) atoms. In the sixth Ta site, Ta(6) is bonded in a 4-coordinate geometry to two equivalent P(1) and two equivalent P(2) atoms. There are three inequivalent P sites. In the first P site, P(3) is bonded in a 8-coordinate geometry to one Ta(1), one Ta(4), two equivalent Ta(2), two equivalent Ta(3), and two equivalent Ta(5) atoms. In the second P site, P(1) is bonded to one Ta(1), one Ta(2), one Ta(3), two equivalent Ta(5), and two equivalent Ta(6) atoms to form distorted edge-sharing PTa7 pentagonal bipyramids. In the third P site, P(2) is bonded in a 9-coordinate geometry to one Ta(1), one Ta(3), one Ta(5), two equivalent Ta(2), two equivalent Ta(4), and two equivalent Ta(6) atoms. is represented by the CIF file [CIF]
