[1] Ionic compound containing iron phthalocyanine (feipc)- anions and (c70-)2 dimers. optical and magnetic properties of (feipc)- in the solid state / D. V. Konarev, A. V. Kuzmin, S. V. Simonov et al. // Dalton Transactions. — 2012. — Vol. 41, no. 45. — P. 13841–13847. Ionic compounds containing the anion of iron phthalocyanine (FeIPc)-, (FeIPc)-[middle dot](cryptand[2,2,2][middle dot][Na+])[middle dot](C6H4Cl2) (1), and the fullerene C70- and FeIPc- anions, (C70-)2[middle dot](FeIPc)-6[middle dot](cryptand[2,2,2][middle dot][Na+])8[middle dot](C6H4Cl2)8.65[middle dot](C6H14)0.35 (2), were obtained as single crystals. Their crystal structures and optical and magnetic properties were analyzed. Spectra of 1 and 2 manifest intense bands in visible-NIR range at 820, 690, 555, 528, 449, 400 and 316 nm attributed to (FeIPc)-. The four-coordinate (FeIPc)- anions show an EPR signal with perpendicular and parallel components at g[bottom] = 2.487 and g[dbl vertical bar] = 2.353 in 1 and g[bottom] = 2.328 and g[dbl vertical bar] = 2.230 in 2. According to magnetic measurements the (FeIPc)- anions have low spin (S = 1/2) state indicating d7 configuration for the FeI atoms with the odd electron on the dz2 orbital. Fullerene anions form singly bonded (C70-)2 dimers in 2, the shape of which efficiently fitted with the large planar phthalocyanine anions to be surrounded completely by eight (FeIPc)- anions. The (C70-)2 dimers are diamagnetic and EPR silent up to 350 K. Both complexes contain channels formed by four (FeIPc)- planes in 1 or four (FeIPc)- planes and two (C70-)2 dimers in 2. The channels are occupied by double chains of alternating cryptand[2,2,2][middle dot][Na+] cations and solvent C6H4Cl2 molecules. [ DOI ]
