TaPNCl7 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two TaPNCl7 clusters. Ta(1) is bonded to one N(1), one Cl(1), one Cl(3), one Cl(5), and two equivalent Cl(2) atoms to form distorted TaNCl5 octahedra that share  a cornercorner with one P(1)NCl3 tetrahedra and  an edgeedge with one Ta(1)NCl5 octahedra. P(1) is bonded to one N(1), one Cl(4), one Cl(6), and one Cl(7) atom to form PNCl3 tetrahedra that share  a cornercorner with one Ta(1)NCl5 octahedra. The corner-sharing octahedral tilt angles are 25°. N(1) is bonded in a bent 150 degrees geometry to one Ta(1) and one P(1) atom. There are seven inequivalent Cl sites. In the first Cl site, Cl(7) is bonded in a single-bond geometry to one P(1) atom. In the second Cl site, Cl(1) is bonded in a single-bond geometry to one Ta(1) atom. In the third Cl site, Cl(2) is bonded in a water-like geometry to two equivalent Ta(1) atoms. In the fourth Cl site, Cl(3) is bonded in a single-bond geometry to one Ta(1) atom. In the fifth Cl site, Cl(4) is bonded in a single-bond geometry to one P(1) atom. In the sixth Cl site, Cl(5) is bonded in a single-bond geometry to one Ta(1) atom. In the seventh Cl site, Cl(6) is bonded in a single-bond geometry to one P(1) atom.
