Figure 3.

X-ray crystal structure of [LMeFeNNFeLMe]− (2) with thermal ellipsoids drawn at the 50% probability level. Orange, blue, and black ellipsoids represent Fe, N, and C atoms, respectively. Hydrogen atoms, a THF molecule of crystallization, and the [K(18-c-6)(THF)2]+ countercation are omitted for clarity. Selected bond distances (Å) and angles (°): Fe(1)–N(1) = 1.744(3); Fe(1)–N(11) = 1.936(2); Fe(1)–N(21) = 1.940(3); N(1)–N(1)* = 1.186(6); N(1)–Fe(1)–N(11) = 131.7(1); N(1)–Fe(1)–N(21) = 128.4(2); N(11)–Fe(1)–N(21) = 98.6(1); N(1)*–N(1)–Fe(1) = 175.2(4).
