The reaction of an electron‐rich transition metal M (M= Ru, Rh, Ir), tellurium and TeX4 (X= Cl, Br, I) resulted in black crystals of five ternary coordination polymers with the general composition MIII (Te6) X3 (M= Rh, Ir) and of the molecular cluster compound RuII2 (Te6)(TeIIBr3) 4 (TeIIBr2) 2. X‐ray diffraction on single‐crystals revealed that the compounds M (Te6) X3 crystallize isostructurally in the trigonal space group type R ̄3 c. In their crystal structures linear, positively charged MIII (Te6) chains form the motif of a hexagonal rod packing. In the chain, each of the formally uncharged Te6 molecules with chair conformation acts as a bis‐tridentate bridging ligand to two M atoms. The octahedrally coordinated M atoms are spiro atoms in the chain of trans vertices sharing heterocubane fragments. Including the isolated halide ions, which provide charge balance, the entire arrangement resembles a cut‐out of the α‐polonium structure type. In the monoclinic compound Ru2Te12Br16 (space group P21/n), the ruthenium atoms of the hetero‐cubane core of the molecular cluster Ru2 (Te6)(TeBr3) 4 (TeBr2) 2 are saturated by terminal bromidotellurate (II) groups. Again, the Te6 ring is formally uncharged. With the tellurium atoms acting as electron‐pair donors the 18 electron rule is fulfilled for the M atoms in all compounds.
