Ti Hg Pd Pd
TiPd2Hg is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TiPd2Hg clusters. Ti(1) is bonded in an L-shaped geometry to two equivalent Pd(1) atoms. Both Ti(1)-Pd(1) bond lengths are 0.30 Å. Pd(1) is bonded in an L-shaped geometry to one Ti(1) and one Hg(1) atom. The Pd(1)-Hg(1) bond length is 0.30 Å. Hg(1) is bonded in an L-shaped geometry to two equivalent Pd(1) atoms.
