title: [Ge₈(Mo(CO)₃)₂]⁴⁻: an unprecedented 20-electron empty ten-vertex Zintl cluster.
abstract: The unprecedented ten-vertex Zintl anion with the two vertices occupied by transition metal fragments, [Ge8(Mo(CO)3)2](4-), has been synthesized and structurally characterized, representing the first example of 20-electron empty ten-vertex Zintl clusters. The two less cluster-bonding electrons result in a markedly distorted bicapped square antiprismatic structure featuring the up-expanded and down-compressed squares.
