NaTbCl4 is Baddeleyite-derived structured and crystallizes in the triclinic P-1 space group. Na(1) is bonded in a 7-coordinate geometry to one Cl(4), two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms. Tb(1) is bonded to one Cl(1), two equivalent Cl(2), two equivalent Cl(3), and two equivalent Cl(4) atoms to form edge-sharing TbCl7 pentagonal bipyramids. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted T-shaped geometry to two equivalent Na(1) and one Tb(1) atom. In the second Cl site, Cl(2) is bonded to two equivalent Na(1) and two equivalent Tb(1) atoms to form a mixture of corner and edge-sharing ClNa2Tb2 trigonal pyramids. In the third Cl site, Cl(3) is bonded to two equivalent Na(1) and two equivalent Tb(1) atoms to form a mixture of corner and edge-sharing ClNa2Tb2 tetrahedra. In the fourth Cl site, Cl(4) is bonded in a distorted trigonal non-coplanar geometry to one Na(1) and two equivalent Tb(1) atoms.
