Reversible Small‐Molecule Interactions with Coordinatively Unsaturated Metal Centers Held in Metallathiaborane Clusters

Abstract: Abstract:The metallathiaboranes [8,8-(dppe) (dppe)] at low temperature (75 % yield). Compound 1 reversibly takes up NH 3 in solution, and the characterization of the resulting compound is discussed. Compound 5 shows no interactions with ammonia but does reversibly take up CO to give [6,6,6-(CO)(dppe)-arachno-6,9-NiSB 8 H 10 ] (7). The

“…Therefore, the CO-ligated system exhibits an opposite behavior compared to that of 2, with the symmetric conformer being the major isomer in solution at all temperatures. The variable-temperature 1 H−{ 11 B} resonances of the cage bridging hydrogen atoms for both compounds also feature similar behavior (Figure S7).…”

“…0.12 Å shortening reflects the smaller covalent radius of Ni (1.24 Å) compared to that of Pd (1.39 Å) . The structure differs considerably from that of thiaborane analogue [8,8-(dppe)- nido -8,7-NiSB 9 H 11 ] in which a B–H vertex is subrogated by a sulfur atom and the two bridging B–H–B hydrogen atoms occupy different positions on the pentagonal open face (schematic structures in Scheme ). These structural changes can be rationalized as a consequence of different metal-to-ligand interactions, a point that is discussed in the next section.…”
