Abstract
Reaction of anhydrous SnCl2 with the nido ten-vertex anions [6,9-C2B8H 10]2-, [6-Me-6,9-C2B8H9]2-, [6-Ph-6,9-C2B8H9]2- or [6,9-Me2-6,9-C2B8H8 ]2- in tetrahydrofuran solution results in the formation of [closo-1,2 ,3-SnC2B8H10] (59%), [2-Me-closo-1,2,3-SnC2B8H9] (34%), [2-Ph-closo-1, 2,3-SnC2B8H9] (21%) or [2,3-Me2-closo-1,2,3-SnC2B8H8] (10%) respective ly as volatile white solids. Their NMR properties suggest that the com pounds are best regarded as true closo species analogous to closo-2,3- C2B9H11.
