The novel eighteen-vertex macropolyhedral dithiaborane anion [S2B16H17]– 1 has been obtained as its [tmndH]+ salt from the reaction of [S2B17H17] 2 and tmnd in solution in the presence of [RhCl2(η5-C5Me5)]2. It has two cluster skeletal electrons more than the three previously reported eighteen-vertex dithiaborane {S2B16} species n-[S2B16H16], n-[S2B16H15]– and iso-[S2B16H16], and the anion consists structurally of an arachno {SB9} and a nido {B9} cluster unit fused with two boron atoms in common, and with an endo-to-exo sulfur bridge that also links the two subclusters together.
