The title compound, (C8H20N)[Fe(C44H28N4)(CN)2]·CH2Cl2 or (Et4N)[Fe(TPP)(CN)2], was recrystallized from dichloromethane-diethyl ether. The compound crystallizes with the two unique halves of the FeIII porphyrinato complex, one tetraethylammonium cation and one interstitial dichloromethane molecule within the asymmetric unit. Both anionic FeIII complexes exhibit inversion symmetry. Both the cation and the solvent molecules show positional disorder. The cation is disordered over two sets of sites with an occupancy ratio of 0.710 (3):0.290 (3); the solvent molecule is disordered over three positions with a 0.584 (6):0.208 (3):0.202 (5) ratio. The crystal packing features columns of [Fe(TPP)(CN)2]- anions that propagate along . The columns further pack into layers that are parallel to (011) and also include the Et4N+ cations. The interstitial CH2Cl2 molecules appear in the interlayer space. This complex may serve as a useful precursor for the assembly of multinuclear and extended CN-bridged complexes for the design of single-molecule and single-chain magnets, respectively.
