Fig. 2. ORTEP diagrams for 2Tol. Hydrogen, boron, carbon, nitrogen, oxygen, and iron atoms are white, pink, grey, light blue, red, and orange respectively. Thermal ellipsoids are shown at the 50% probability level. Calculated hydrogen atoms are omitted for clarity except those on atom N10. The hydrogen bonding interaction is shown in red. Selected bond distances (Å): Fe–N1, 2.036(3); Fe–N2, 1.986(3); Fe–N4, 1.963(3); Fe–N10, 1.859(3); N10–C1, 1.330(4); C2–O, 1.240(5); C1–C2, 1.484(5); C2–C3, 1.477(5); C3–C4, 1.353(6); C4–C5, 1.437(6); C5–C6, 1.357(5); C6–C1, 1.429(5); O–H, 2.145(4). Selected bond angles (°): N1–Fe–N2, 91.6(1); N2–Fe–N4, 92.9(1); N1–Fe–N10, 178.1(1); Fe–N10–C1, 136.2(2). Further metrical data are given in Table S1.‡.
