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

ABSTRACT: 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.

Topology analysis reveals this compound to be a (4,4)-connected network.

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.

Crystal structure of (diethyl ether-κO)[5,10,15,20-tetra-kis-(2-iso-thio-cyanato-phen-yl)porphyrinato-κ4 N]zinc diethyl ether solvate.

Project description:The crystal structure of the title compound, [Zn(C48H24N8S4)(C4H10O)]·C4H10O, consists of discrete porphyrin complexes that are located on a twofold rotation axis. The ZnII cation is fivefold coordinated by four N atoms of the porphyrin moiety and one O atom of a diethyl ether mol-ecule in a slightly distorted square-pyramidal environment with the diethyl ether mol-ecule in the apical position. The porphyrin backbone is nearly planar with the metal cation slightly shifted out of the plane towards the coordinating diethyl ether mol-ecule. All four iso-thio-cyanato groups of the phenyl substituents at the meso-positions face the same side of the porphyrin, as is characteristic for picket fence porphyrins. In the crystal structure, the discrete porphyrin complexes are arranged in such a way that cavities are formed in which additional diethyl ether solvate mol-ecules are located around a twofold rotation axis. The O atom of the solvent mol-ecule is not positioned exactly on the twofold rotation axis, thus making the whole mol-ecule equally disordered over two symmetry-related positions.

Crystal structure of nitrido[5,10,15,20-tetra-kis(4-methylphenyl)-porphyrinato]-manganese(V).

Project description:The title compound, [Mn(C48H36N4)(N)], is a manganese(V) complex with the transition metal in a square-pyramidal coordination geometry and a nitride as the axial ligand.

The Mn N distance is 1.516?(4)?Å. The Mn(V) atom is displaced from the plane defined by the four equatorial nitro-gen atoms toward the nitride ligand by 0.3162?(6)?Å.

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

Project description: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.
