| - The chemistry of p-block metallacarboranesof the C2B10 systems is largely unexplored in comparisonwith that of s-, d-, and f-block metallacarboranes. Thisarticle reports several carbons-adjacent stannacarboranes of the C2B10 system and their chemical propertiesfor the first time. Reaction of SnCl2 with [{μ-1,2-[o-C6H4(CH2)2]-1,2-C2B10H10}2Na4(THF)6]n gave the Lewis basefree stannacarborane {μ-1,2-[o-C6H4(CH2)2]-1,2-C2B10H10}Sn (1). Recrystallization of 1 from MeCN, THF, andDME afforded the corresponding Lewis base coordinatedstannacarboranes {μ-1,2-[o-C6H4(CH2)2]-1,2-C2B10H10}Sn(MeCN) (2), {μ-1,2-[o-C6H4(CH2)2]-1,2-C2B10H10}Sn(THF)·THF (3·THF), and {μ-1,2-[o-C6H4(CH2)2]-1,2-C2B10H10}Sn(DME) (4), respectively. They were fullycharacterized by various spectroscopic data and elemental analyses. Complexes 2−4 were further confirmed bysingle-crystal X-ray analyses.
