Isomers of B20H26: elucidation of the structure of 6,6′-Bi(nido-decaboranyl) by 11B-{1H} and 1H-{11B} n.m.r. spectroscopy
Abstract
The structure of one of the B20H26 isomers formed by thermolysis of nido-decaborane in the presence of tetrahydrothiophen has been shown to be 6,6′-bi(nido-decaboranyl) by means of 1H-{11B} n.m.r. spectroscopy in conjuction with ‘partially relaxed’11B and 11B-{1H} n.m.r. spectroscopy; it is the largest neutral borane yet characterised.
