Ga Ga Ni Pb
PbNi1(Ga)2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two gallium molecules and two PbNi1 clusters. In each PbNi1 cluster, Ni(1) is bonded in a single-bond geometry to one Pb(1) atom. The Ni(1)-Pb(1) bond length is 0.45 Å. Pb(1) is bonded in a single-bond geometry to one Ni(1) atom.
