In an attempt to build up borane-based multicluster assemblies, thermolysis of [6,9-(SMe2)2-arachnoB10H 12] 1 in inert hydrocarbon solution, followed by chromatographic separation, has resulted in the isolation not only of the previously established single-cluster product from this reaction, [5-(SMe 2)-nido-B10H12] 2 (30%), but also the two two-cluster species [6,9-(SMe2)2-arachno-B 10H11-l-(6′-nido-B10H13)] 3 (20%) and [l,6′-(nido-B10H13)2] 6 (ca. 0.5%) and the two three-cluster species [6,9-(SMe2) 2-arachno-B10H10-l,5-(6′-nido-B 10H13)2] 4 (5%), characterized crystallographically, and [6,9-(SMe2)2-arachno-B 10H10-l,3-(6′-nido-B10H 13)2] 5 (2)-nido-B 10H12] 2 is also presented. The feasibility of the stability of species resulting from multiple adjacent substitution of nido-decaboranyl units on the [6,9-(SMe2)2-arachno-B 10H12] skeleton is tested by DFT calculations. In an extension, to attempt the use of pre-a-linked two-cluster compounds as starting substrates, two-cluster [5-(SMe2)-4-(2′-nido-B 10H13)-nido-B10H11] 7 (0.6%) has been isolated from the reaction of SMe2 with [1,5′-(nido-B 10H13)2], other identified products being compound 1 (39%) and compound 3 (10.5%).
