T. Jelinek et al., MACROPOLYHEDRAL BORON-CONTAINING CLUSTER CHEMISTRY - CLUSTER FUSION TO GIVE THE NOVEL NIDO-NIDO 18-VERTEX DITHIAOCTADECABORANE (ANTI)-[9,9'-S2B16H16], Journal of the Chemical Society, Chemical Communications, (12), 1994, pp. 1415-1416
Thermolysis of arachno-4-SB8H12 in cyclohexane generates the eighteen-
vertex dithiaborane (anti)-[9,9'-S2B16H16]dagger via a simple cluster
fusion previously unrealized for heteroborane species.
