B2PTe2 crystallizes in the monoclinic Cm space group. There are two inequivalent B sites. In the first B site, B(1) is bonded to one B(2), one P(1), and two equivalent Te(1) atoms to form a mixture of edge and corner-sharing BBTe2P tetrahedra. The B(1)-B(2) bond length is 1.39 Å. The B(1)-P(1) bond length is 2.21 Å. Both B(1)-Te(1) bond lengths are 1.71 Å. In the second B site, B(2) is bonded to one B(1), one P(1), and two equivalent Te(1) atoms to form a mixture of distorted edge and corner-sharing BBTe2P tetrahedra. The B(2)-P(1) bond length is 1.32 Å. Both B(2)-Te(1) bond lengths are 1.69 Å. P(1) is bonded in a distorted single-bond geometry to one B(1), one B(2), and two equivalent Te(1) atoms. Both P(1)-Te(1) bond lengths are 2.68 Å. Te(1) is bonded in a 3-coordinate geometry to one B(1), one B(2), and one P(1) atom.
