RESUMO
In the title salt, [Mn(C44H28N4)(H2O)](CF3SO3) or [Mn(III)(TPP)(H2O)](CF3SO3) (where TPP is the dianion of 5,10,15,20-tetra-phenyl-porphyrin), the Mn(III) cation is chelated by the four pyrrole N atoms of the porphyrinate anion and additionally coordinated by an aqua ligand in an apical site, completing the distorted square-pyramidal coordination environment. The average Mn-N(pyrrole) bond length is 1.998â (9)â Å and the Mn-O(aqua) bond length is 2.1057â (15)â Å. The central Mn(III) ion is displaced by 0.1575â (5)â Å from the N4C20 mean plane of the porphyrinate anion towards the apical aqua ligand. The porphyrinate macrocycle exhibits a moderate ruffling and strong saddle deformations. In the crystal lattice, the [Mn(III)(TPP)(H2O)](+) cation and the tri-fluoro-methane-sulfonate counter-ions are arranged in alternating planes packed along [001]. The components are linked together through O-Hâ¯O hydrogen bonds and much weaker C-Hâ¯O and C-Hâ¯F inter-actions. The crystal packing is further stabilized by weak C-Hâ¯π inter-actions involving the pyrrole and phenyl rings of the porphyrin moieties.
RESUMO
In the title compound, [Fe(II)(C44H24Cl4N4)(C6H5CH2NH2)2]·C6H14 or [Fe(II)(TPP-Cl)(BzNH2)2]·n-hexane [where TPP-Cl and BzNH2 are 5,10,15,20-tetra-kis-(4-chloro-phen-yl)porphyrinate and benzyl-amine ligands, respectively], the Fe(II) cation lies on an inversion centre and is octa-hedrally coordinated by the four pyrrole N atoms of the porphyrin ligand in the equatorial plane and by two amine N atoms of the benzyl-amine ligand in the axial sites. The crystal structure also contains one inversion-symmetric n-hexane solvent mol-ecule per complex mol-ecule. The average Fe-Npyrrole bond length [1.994â (3)â Å] indicates a low-spin complex. The crystal packing is sustained by N-Hâ¯Cl and C-Hâ¯Cl hydrogen-bonding inter-actions and by C-Hâ¯π inter-molecular inter-actions, leading to a three-dimensional network structure.
RESUMO
In the title compound, [Mn(C44H28N4)Cl]·2C5H6N2, the Mn(III) centre is coordinated by four pyrrole N atoms [averaged Mn-N = 2.012â (4)â Å] of the tetra-phenyl-porphyrin mol-ecule and one chloride axial ligand [Mn-Cl = 2.4315â (7)â Å] in a square-pyramidal geometry. The porphyrin macrocycle exhibits a non-planar conformation with major ruffling and saddling distortions. In the crystal, two independent solvent mol-ecules form dimers through N-Hâ¯N hydrogen bonding. In these dimers, one amino N atom has a short Mnâ¯N contact of 2.642â (1)â Å thus completing the Mn environment in the form of a distorted octa-hedron, and another amino atom generates weak N-Hâ¯Cl hydrogen bonds, which link further all mol-ecules into chains along the a axis.
