The metal‐rich antimonide Zr 2 V 6 Sb 9 has been prepared by arc‐melting of stoichiometric mixtures of Zr, V, and VSb 2 . Zr 2 V 6 Sb 9 is the first example of a ternary ordered (filled) variant of the unusual V 15 Sb 18 structure type. In addition to strong metal–antimony bonding, the crystal structure is significantly stabilized by bonding V–V and Sb–Sb interactions, whereas the Zr atoms do not form short metal–metal bonds. Band structure calculations using the Extended Hückel approximation reveal Zr 2 V 6 Sb 9 being metallic, in agreement with the Pauli paramagnetism experimentally observed.
