Ta Pd Cl Cl
TaPdCl2 crystallizes in the trigonal R3m space group. Ta(1) is bonded in a 7-coordinate geometry to one Pd(1), three equivalent Cl(1), and three equivalent Cl(2) atoms. The Ta(1)-Pd(1) bond length is 1.97 Å. All Ta(1)-Cl(1) bond lengths are 2.73 Å. All Ta(1)-Cl(2) bond lengths are 2.73 Å. Pd(1) is bonded in a 1-coordinate geometry to one Ta(1), three equivalent Cl(2), and four equivalent Cl(1) atoms. All Pd(1)-Cl(2) bond lengths are 2.73 Å. There is one shorter (2.55 Å) and three longer (2.83 Å) Pd(1)-Cl(1) bond lengths. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 8-coordinate geometry to three equivalent Ta(1), four equivalent Pd(1), and one Cl(2) atom. The Cl(1)-Cl(2) bond length is 1.97 Å. In the second Cl site, Cl(2) is bonded in a 7-coordinate geometry to three equivalent Ta(1), three equivalent Pd(1), and one Cl(1) atom.
