Abstract

New bidentate and tridentate ligands that feature selenium donors, namely the bis- and tris(2-seleno-1-methylimidazolyl)hydroborato ligands Bse Me and TseMe, have been constructed via the reaction of MBH4 (M = Na, K) with 1-methylimidazole-2-selone. Comparison of the structure of {BseMeZnI}2 with its sulfur counterpart, BmMeZnI, demonstrates that the seleno ligand exhibits a greater tendency than the mercapto ligand to bridge two metal centers, while comparison of TseMeRe(CO)3 and TseMesRe(CO)3 indicates that the TseMe ligand is more electron donating and less sterically demanding than the TseMes ligand.
