Abstract

The synthesis of the Cu-borate complexes [(6Mes)Cu(HBR3)] featuring the unusual [HBEt3]− (5) and [HB(C6F5)3]− (6) ligands is described. Experimental and computational studies show both compounds feature a direct Cu–H interaction, but that while 5 is two-coordinate, 6 displays an additional, stabilizing Cu–Cipso(C6F5) interaction.
