Chlorido(pyridine-?N)(5,10,15,20-tetra-phenyl-porphyrinato-?(4)N)cobalt(III) chloro-form hemisolvate.

ABSTRACT: In the title complex, [CoCl(C(44)H(28)N(4))(C(5)H(5)N)]·0.5CHCl(3) or [Co(III)(TPP)Cl(py)]·0.5CHCl(3) (where TPP is the dianion of tetra-phenyl-porphyrin and py is pyridine), the average equatorial cobalt-pyrrole N atom bond length (Co-N(p)) is 1.958?(7)?Å and the axial Co-Cl and Co-N(py) distances are 2.2339?(6) and 1.9898?(17)?Å, respectively. The tetra-phenyl-porphyrinate dianion exhibits an important nonplanar conformation with major ruffling and saddling distortions. In the crystal, mol-ecules are linked via weak C-H?? inter-actions. In the difference Fourier map, a region of highly disordered electron density was estimated using the SQUEEZE routine [PLATON; Spek (2009 ?), Acta Cryst. D65, 148-155] to be equivalent to one half-mol-ecule of CHCl(3) per mol-ecule of the complex.

Crystal structure of chlorido-(5,10,15,20-tetra-phenyl-porphyrinato-?(4) N)manganese(III) 2-amino-pyridine disolvate.

Project description:In the title compound, [Mn(C44H28N4)Cl]·2C5H6N2, the Mn(III) centre is coordinated by four pyrrole N atoms [averaged Mn-N = 2.012?(4)?Å] of the tetra-phenyl-porphyrin mol-ecule and one chloride axial ligand [Mn-Cl = 2.4315?(7)?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-H?N hydrogen bonding. In these dimers, one amino N atom has a short Mn?N contact of 2.642?(1)?Å thus completing the Mn environment in the form of a distorted octa-hedron, and another amino atom generates weak N-H?Cl hydrogen bonds, which link further all mol-ecules into chains along the a axis.

(5,10,15,20-Tetra-phenyl-porphyrinato-?N)cobalt(II)-18-crown-6 (1/1).

Project description:The asymmetric unit of the title compound, [Co(C(44)H(28)N(4))]·C(12)H(24)O(6), contains one half of a Co(II)(TPP) (TPP is tetra-phenyl-porphyrin) complex and one half of an 18-crown-6 mol-ecule of crystallization, both lying on inversion centers. The Co(II)(TPP) complex exhibits a nearly planar conformation of the porphyrinate core [maximum deviation = 0.069?(2)?Å] with an average Co-N distance of 1.971?(4)?Å. The distance between the Co atom and the closest O atom of the 18-crown-6 mol-ecule is 2.533?(2)?Å, indicating a short non-bonded contact between the Co atom and the crown ether mol-ecule. An ethyl-ene group of the 18-crown-6 mol-ecule is disordered over two sites with occupancies of 0.565?(7) and 0.435?(7).

Tetra-ethyl-ammonium dicyanido(5,10,15,20-tetra-phenyl-porphyrinato)ferrate(III) di-chloro-methane monosolvate.

Project description:The title compound, (C8H20N)[Fe(C44H28N4)(CN)2]·CH2Cl2 or (Et4N)[Fe(TPP)(CN)2], was recrystallized from di-chloro-methane-diethyl ether. The compound crystallizes with the two unique halves of the Fe(III) porphyrinato complex, one tetra-ethyl-ammonium cation and one inter-stitial di-chloro-methane mol-ecule within the asymmetric unit. Both anionic Fe(III) complexes exhibit inversion symmetry. Both the cation and the solvent mol-ecules 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 mol-ecule 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 inter-stitial CH2Cl2 mol-ecules appear in the inter-layer space. This complex may serve as a useful precursor for the assembly of multinuclear and extended CN-bridged complexes for the design of single-mol-ecule and single-chain magnets, respectively.

Project description:The title compound, [Fe(C44H28N4)(C6HF4O)], is a porphyrin complex with iron(III) in fivefold coordination with a tetra-fluoro-phenolate group as the axial ligand. The Fe atom and the phenolate ligand are disordered across the porphyrin ring with the two phenolates appearing to be roughly related by a center of symmetry. The occupancies of the two phenolate groups refined to 0.788?(3) for the major component and 0.212?(3) for the minor component. The structure shows extraordinary Fe displacements of 0.488?(4) (major) and 0.673?(4)?Å (minor) from the 24-atom mean plane of the porphyrin. The Fe-Np distances range from 2.063?(4) to 2.187?(6)?Å and the Fe-O distances are 1.903?(5)?Å for major component and 1.87?(2)?Å for minor component. The four phenyl groups attached to the porphyrin ring form dihedral angles of 63.4?(4), 49.6?(4), 62.4?(4), and 63.3?(4)° (in increasing numerical order) with the three nearest C atoms of the porphyrin ring. The major and minor component phenolate groups form dihedral angles of 24.9?(4)° and 24.8?(4)°, respectively, with the four porphyrin N atoms. The Fe?Fe distance between the two iron(III) atoms of adjacent porphyrin mol-ecules is 6.677?(3)?Å. No close inter-molecular inter-action was observed. The crystal studied was twinned by inversion, with a major-minor component ratio of 0.53?(3):0.47?(3).

Dichlorido(5,10,15,20-tetra-phenyl-porphyrinato-?(4)N)anti-mony(V) hemi{di-?-chlorido-bis-[trichloridoanti-monate(III)]} dichloro-methane monosolvate.

Project description:The asymmetric unit of the title complex, [Sb(C(44)H(28)N(4))Cl(2)][Sb(2)Cl(8)](0.5)·CH(2)Cl(2), is composed of a Sb(V) complex cation wherein the Sb atom is hexa-coordinated by four N atoms of the pyrrole rings of the tetra-phenyl-porphyrinate (TPP) ligands and two chloride ions, a half di-?-chlorido-bis-[trichloridoanti-monate(III)] counter-anion and a dichloro-methane solvent mol-ecule. In the cation, the average Sb-N distance is 2.066?(2)?Å, while the Sb-Cl distances are 2.3410?(11) and 2.3639?(12)?Å. The central unit of the cation, SbN(4)C(20), is far from being planar, with deviations of atoms from the least-squares plane ranging from -0.110?(4) to 0.124?(4)?Å. The Sb-Cl distances in the anion, which is located about an inversion center, lie in the wide range 2.3715?(13)-2.7489?(13)?Å, the longest distances being between the Sb and bridging Cl atoms. The crystal structure is stabilized by inter-molecular C-H?Cl inter-actions involving the cations, the anions and the solvent mol-ecules. The solvent mol-ecule is disordered over two orientations in a 0.901?(13):0.099?(13) ratio.
