Chemically facile loss of MeCN ligands in [M II (NCMe) 6 ][TFPB] 2 {M=V, Cr, Mn, Fe, Co, Ni; [TFPB] − =tetrakis[3,5‐bis(trifluoromethyl)phenyl]borate} leads to an excellent source of “naked” divalent first‐row metal ions. These salts are thermally stable up to 130 °C (figure). Loss of the first MeCN leads to an η 2 nitrile. From an analysis of the ligand field parameters MeCN is a stronger field ligand than H 2 O, but slightly weaker than NH 3 .
