Heterometallic cluster compounds are currently actively investigated by many research groups, leading from structural studies through functional analyses to the generation of innovative materials.[1,2] Binary anionic P4 analogs, [E142E152]2– and [E13E153]2– (E13 = Ga, In, Tl; E14 = Ge, Sn, Pb; E15 = As, Sb, Bi), hence binary tetrahedral Zintl-anions, proved to be useful synthetic tools in reactions with transition metal compounds for assembling ternary intermetalloid clusters [MxE13/14yE14/15z]q–.[3,4] The latter possess a large variety of different structural motifs and corresponding electronic properties, depending on the nature of the involved elements.[5-8] Unprecedented, non-classical structures helped to gain deeper insight in the formation of such aggregates.[9.10]
