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.

Project description:In the mol-ecule of the title compound, [Co(C(44)H(24)Cl(4)N(4)){(C(4)H(9))(3)P}(2)]ClO(4), the Co(III) centre has a slightly distorted octa-hedral geometry and is coordinated by four N atoms of the tetra-pyrrolic ring in the equatorial positions and two phosphine ligands in the axial positions. The dihedral angles between meso-substituted chloro-phenyl rings and the basic tetra-pyrrolic ring are 82.66 (9), 82.16 (7), 83.97 (11) and 76.87 (8)°. In one of the phosphine ligands, the two terminal methyl groups are disordered over two positions with refined site-occupancy ratios of 0.70 (7):0.30 (7) and 0.66 (2):0.34 (2). In the crystal structure, mol-ecules are linked together along the a axis by inter-molecular C-H⋯Cl inter-actions. The crystal structure is further stabilized by intra-molecular C-H⋯O and C-H⋯N inter-actions and inter-molecular C-H⋯O and C-H⋯π inter-actions.

(1-Methyl-1H-imidazole-κN (3))(1-methyl-2-nitroso-benzene-κN)(5,10,15,20-tetra-phenyl-porphyrinato-κ(4) N)iron(II) di-chloro-methane monosolvate.

Project description:The solvated title compound, [Fe(C44H28N4)(C4H6N2)(C7H7NO)]·CH2Cl2, is a porphyrin complex containing an octahedrally coordinated Fe(II) atom with 1-methylimidazole [Fe-N = 2.0651 (17) Å] and o-nitro-sotoluene ligands at the axial positions. The o-nitro-sotoluene ligand is N-bound to iron(II) [Fe-N = 1.8406 (18)Å and Fe-N-O = 122.54 (14)°]. The axial N-Fe-N linkage is almost linear, with a bond angle of 177.15 (7)°. One phenyl group of the porphyrin ligand is disordered over two orientations in a 0.710 (3):0.290 (3) ratio. The di-chloro-methane solvent mol-ecule was severely disordered and its contribution to the scattering was removed with the SQUEEZE routine [van der Sluis & Spek (1990 ▶). Acta Cryst. A46, 194-201].

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.

Crystal structure of bis-(benzyl-amine-κN)[5,10,15,20-tetra-kis-(4-chloro-phen-yl)porphyrinato-κ(4) N]iron(II) n-hexane monosolvate.

Project description: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 [1.994 (3) Å] indicates a low-spin complex. The crystal packing is sustained by N-H⋯Cl and C-H⋯Cl hydrogen-bonding inter-actions and by C-H⋯π inter-molecular inter-actions, leading to a three-dimensional network structure.

Chlorido{5,10,15,20-tetra-kis-[2-(2,2-dimethyl-propanamido)-phen-yl]porphyrinato-?N,N',N'',N'''}iron(III) chloro-benzene hemisolvate monohydrate.

Project description:In the title complex, [Fe(C(64)H(64)N(8)O(4))Cl]·0.5C(6)H(5)Cl·H(2)O, the equatorial iron-pyrrole N atom distance (Fe-N(p)) is 2.065?(2)?Å and the axial Fe-Cl distance is 2.207?(2)?Å. The iron cation is displaced by 0.420?(4)?Å from the 24-atom mean plane of the porphyrin core.

Crystal structure of (4-cyano-pyridine-κN){5,10,15,20-tetrakis[4-(benzoyloxy)phenyl]porphyrinato-κ(4) N}zinc-4-cyano-pyridine (1/1).

Project description:In the title compound, [Zn(C72H44N4O8)(C6H4N2)]·C6H4N2 or [Zn(TPBP)(4-CNpy]·(4-CNpy) [where TPBP and 4-CNpy are 5,10,15,20-(tetra-phenyl-benzoate)porphyrinate and 4-cyano-pyridine, respectively], the Zn(II) cation is chelated by four pyrrole-N atoms of the porphyrinate anion and coordinated by a pyridyl-N atom of the 4-CNpy axial ligand in a distorted square-pyramidal geometry. The average Zn-N(pyrrole) bond length is 2.060 (6) Å and the Zn-N(4-CNpy) bond length is 2.159 (2) Å. The zinc cation is displaced by 0.319 (1) Å from the N4C20 mean plane of the porphyrinate anion toward the 4-cyano-pyridine axial ligand. This porphyrinate macrocycle exhibits major saddle and moderate ruffling and doming deformations. In the crystal, the [Zn(TPBP)(4-CNpy)] complex mol-ecules are linked together via weak C-H⋯N, C-H⋯O and C-H⋯π inter-actions, forming supra-molecular channels parallel to the c axis. The non-coordinating 4-cyano-pyridine mol-ecules are located in the channels and linked with the complex mol-ecules, via weak C-H⋯N inter-actions and π-π stacking or via weak C-H⋯O and C-H⋯π inter-actions. The non-coordinating 4-cyano-pyridine mol-ecule is disordered over two positions with an occupancy ratio of 0.666 (4):0.334 (4).

[meso-5,10,15,20-Tetra-kis(3-methyl-thio-phen-2-yl)porphyrinato-κ(4) N,N',N'',N''']nickel(II) benzene hemisolvate.

Project description:In the title compound, [Ni(C40H28N4S4)]·0.5C6H6, the Ni(II) atom is in a square-planar geometry defined by four pyrrole N atoms. There is considerable buckling in the porphyrin ring with the dihedral angles between the N4 donor set and the pyrrole rings being in the range 16.24 (5)-22.47 (5)°. Each of the six-membered chelate rings is twisted about an Ni-N bond and the dihedral angles between diagonally opposite chelate rings are 21.36 (4) and 23.87 (4)°; each pair of rings is oriented in opposite directions. The methyl-thienyl rings are twisted out of the plane of the central N4 core with dihedral angles in the range 75.98 (2)-88.70 (5)°. All four methyl-thienyl groups are disordered over two sets of sites, as is commonly found with such groups, with occupancies of 0.553 (8):0.447 (8), 0.579 (7):0.421 (7), 0.796 (6):0.204 (6) and 0.956 (7):0.044 (7). The benzene solvent mol-ecule was found to be present in half-occupancy.

Di-chlorido-(5,10,15,20-tetra-phenyl-porphyrinato-?(4) N)anti-mony(V) hexa-chlorido-anti-monate(V).

Project description:The asymmetric unit of the title compound, [Sb(C44H28N4)Cl2][SbCl6], consists of one half of an anti-mony(V) tetra-phenyl-porphyrin complex cation and one half of an hexa-chlorido-anti-monate(V) anion. In the complex cation, the Sb(V) atom lies on an inversion center and is octa-hedrally coordinated by four N atoms from a macrocyclic tetra-phenyl-porphyrinate ligand and two chloride ions. The complex cation has approximately a planar core with a maximum deviation of 0.018?(5)?Å from the porphyrin mean plane. The average Sb-N distance is 2.062?(11)?Å, while the Sb-Cl distance is 2.355?(1)?Å. The Sb(V) atom of the anion is also located on an inversion center. The [SbCl6](-) octa-hedron exhibits rhombic distortion characterized by the Sb-Cl bond lengths [2.311?(3), 2.374?(2) and 2.393?(4)?Å]. In the crystal, the cations and anions are linked C-H? Cl hydrogen bonds, forming a layer parallel to (211).

(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.
