The crystal structure of the title compound, C44H22F8N4, shows an unusual non-planar geometry of the porphyrin ring although the mol-ecule is free of steric crowding around the periphery of the macrocycle. The mol-ecular packing exhibits weak inter-molecular hydrogen bonding (C - H⋯F) and C - H⋯π inter-actions. The molecular symmetry is . © International Union of Crystallography 2008.

Crystallographic studies of the fluorinated tetraarylporphyrin 5,10,15,20-tetrakis(2′,3′,5′,6′-tetrafluoro-N,N-dimethyl-4-anilinyl)porphyrin and its metal complexes [MTF4DMAP; M = 2H·2H2O, 1; NiII·THF, 2; CuII·5H2O, 3; and ZnII·(THF)2, 4; THF = tetrahydrofuran] are reported. To analyse the weak intermolecular interactions, we have used a combination of energy decomposition analysis and Hirshfeld surface analysis, which allowed us to elucidate the nature of various close contacts. The energy decomposition analysis shows that dispersive interactions involving fluorine atoms significantly contribute to the stabilizing intermolecular interactions. Cooperative weak interactions such as C-F⋯H/C/F, C-H⋯π and H⋯H are responsible for the formation and stabilization of the supramolecular self assemblies. Hirshfeld surface and energy decomposition analyses of metalloporphyrins show that dispersive interactions involving fluorine atoms are the major contributors to the molecular crystal packing.

Intermolecular interactions in fluorinated tetraarylporphyrins: An experimental and theoretical study

Crystallographic studies of the fluorinated tetraarylporphyrin 5,10,15,20-tetrakis(2′,3′,5′,6′-tetrafluoro-N, N-dimethyl-4-anilinyl)porphyrin and its metal complexes [MTF4DMAP; M = 2H·2H2O, 1; NiII·THF, 2; Cu II·5H2O, 3; and ZnII·(THF) 2, 4; THF = tetrahydrofuran] are reported.

The energy decomposition analysis shows that dispersive interactions involving fluorine atoms significantly contribute to the stabilizing intermolecular interactions. Cooperative weak interactions such as C-F···H/C/F, C-H···π and H···H are responsible for the formation and stabilization of the supramolecular self assemblies. © 2014 WILEY-VCH Verlag GmbH &amp; Co.
