Macropolyhedral boron-containing cluster chemistry. Aspects of the S2B16H16 system. Preparation, structure, NMR spectroscopy and isomerism.

Original language description

Thermolysis of [arachno-4-SB8H12] (1) in boiling cyclohexane gives two isomers 2 and 3 of 18-vertex [S2B16H16], together with known 12-vertex [closo-1-SB11H11] (4) and known 11-vertex [nido-7-SB10H12] (5). Compounds 2 and 3 are characterised by single-crystal X-ray diffraction analyses and single- and double-resonance B-11- and H-1-NMR spectroscopy. The [n-S2B16H16] isomer 2 takes the form of nido ten-vertex: nido ten-vertex [anti-B18H22] with the 9 and 9' positions occupied by S vertices, whereas the [iso-S2B16H16] isomer 3 takes the form of a nido 11-vertex {SB10} subcluster fused via a common two-boron edge to a nido-type {B-8} subcluster that is additionally linked exo to the {SB10} subcluster by a bridging S atom that is held endo to the {B-8} unit. Isomer 2 is readily deprotonated and its monoanion 6 is characterised by NMR spectroscopy and by a single-crystal X-ray diffraction analysis of its [tmndH](+)[n-S2B16H15] salt 6b; deprotonation has occurred from an open-face B-H-B brid
