Abstract

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