Method
as for [FeL2][BF4]2, using bpp (50 mg, 0.24 mmol), Fe[CF3SO3]2 (42 mg, 0.12 mmol), and acetonitrile
(5 cm3). The crude material is hygroscopic and must be
recrystallized from dried solvent, but its single crystals are more
stable under ambient conditions. Yellow prisms were obtained by diffusion
of diethyl ether vapor into a solution of the complex in nitromethane,
containing the drying agent triethyl orthoformate. Yield 76 mg, 82%.
Found C, 37.2; H, 2.34; N, 17.6%. Calcd for C24H18F6FeN10O6S2 C, 37.1;
H, 2.34; N, 18.0%. Full characterization of other salts of [Fe(bpp)2]2+ can be found in ref (31 (link)).
