Tetra­ethyl­ammonium dicyanido(5,10,15,20-tetra­phenyl­porphyrinato)ferrate(III) di­chloro­methane monosolvate

Abstract: 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 [001]. 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.
