"The addition of elemental sulphur to the 10-vertex nido dicarborane [6,9-C(2)B(8)H10](2-)(2) engenders the new 11-vertex species [1,6,7-C2SB8H11](-) (2), which has been structurally characterised using the ab initio/GIAO/NMR method and by deductions made from observations on its reaction chemistry. These combined studies revealed 2 to adopt a structure that is formally derived from the hypothetical parent [closo-B13H13](2-) anion by removal of two adjacent six-coordinate and five-coordinate vertices. Since the GIAO calculations of B-11 and C-13 chemical shifts, employing the RMP2/6-31G* geometry, showed an excellent agreement with the experimental findings, in particular those for delta(B-11) and delta(C-13) that were computed at the GIAO-RMP2/II' level, the RMP2/6-31G* parameters can be deemed a good representation of the molecular structure of 2 in solution. The other possible structural alternatives of 2 could be ruled out on the basis of geometrical, energetic, and NMR criteria." . . "RIV/61388980:_____/03:50033039" .
