Ta As Pd Pd
TaPd2As crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TaPd2As clusters. Ta(1) is bonded in a 2-coordinate geometry to two equivalent Pd(1) atoms. Both Ta(1)-Pd(1) bond lengths are 0.58 Å. Pd(1) is bonded in a 2-coordinate geometry to one Ta(1), one Pd(1), and one As(1) atom. The Pd(1)-Pd(1) bond length is 0.36 Å. The Pd(1)-As(1) bond length is 1.04 Å. As(1) is bonded in a 2-coordinate geometry to two equivalent Pd(1) atoms.
