文摘

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–C_ipso(C₆F₅) interaction.
