Homoleptic Cobalt(II) and Cobalt(III) Complexes of the Sterically Demanding Bidentate Ligand N-ethyl-2-(2′-hydroxy-3′-methylphenyl)benzimidazole
Homoleptic cobalt(II) and cobalt(III) complexes of the sterically demanding bidentate ligand N-ethyl-2-(2′-hydroxy-3′-methylphenyl)-benzimidazole (H-ehmpb) are reported. The bis-ligand cobalt(II) complex Co(ehmpb)2 has a distorted tetrahedral geometry with Co-N bond lengths of 1.982(3) and 1.976(3) Å, and Co-O bond lengths of 1.915(2) and 1.930(2) Å. The tris-ligand cobalt(III) complex Co(ehmpb)3 has a distorted mer-octahedral geometry with Co-N bond lengths of 1.879(6), 1.897(6), and 1.895(6) Å, and Co-O bond lengths of 1.923(7), 1.937(7), and 1.937(7) Å.
