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.

ABSTRACT: 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 Zn^II 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 an unknown solvate of (piperazine-κN){5,10,15,20-tetra-kis-[4-(benzo-yloxy)phen-yl]porphyrinato-κ(4) N}zinc.

Project description:The title compound, [Zn(C72H44N4O8)(C4H10N2)] or [Zn(TPBP)(pipz] (where TPBP and pipz are 5,10,15,20-tetra-kis-[4-(benzo-yloxy)phen-yl]porphyrinato and piperazine ligands respectively), features a distorted square-pyramidal coordin-ation geometry about the central Zn(II) atom. This central atom is chelated by the four N atoms of the porphyrinate anion and further coordinated by a nitro-gen atom of the piperazine axial ligand, which adopts a chair confirmation. The average Zn-N(pyrrole) bond length is 2.078 (7) Å and the Zn- N(pipz) bond length is 2.1274 (19) Å. The zinc cation is displaced by 0.4365 (4) Å from the N4C20 mean plane of the porphyrinate anion toward the piperazine axial ligand. This porphyrinate macrocycle exhibits major saddle and moderate ruffling deformations. In the crystal, the supra-molecular structure is made by parallel pairs of layers along (100), with an inter-layer distance of 4.100 Å while the distance between two pairs of layers is 4.047 Å. A region of electron density was treated with the SQUEEZE [Spek (2015 ▸). Acta Cryst. C71, 9-18] procedure in PLATON following unsuccessful attempts to model it as being part of disordered n-hexane solvent and water mol-ecules. The given chemical formula and other crystal data do not take into account these solvent mol-ecules.

Redetermination of cyclo-tetra-kis-(?-5,10,15,20-tetra-4-pyridyl-porphyrinato)tetra-zinc(II) dimethyl-formamide octa-solvate trihydrate at 100?K.

Project description:The structure of the title compound, [Zn(4)(C(40)H(24)N(8))(4)]·8C(3)H(7)NO·3H(2)O, has been redetermined at 100?K. The redetermination is of significantly higher precision and gives further insight into the disorder of pyridyl groups and solvent mol-ecules. The mol-ecules of (5,10,15,20-tetra-4-pyridyl-porphyrinato)zinc(II) (ZnTPyP) form homomolecular cyclic tetra-mers by coordination of a peripheral pyridyl group to the central Zn atom of an adjacent symmetry-related mol-ecule. The tetra-mer so formed exhibits mol-ecular S(4) symmetry and is located about a crystallographic fourfold rotoinversion axis. Severely disordered dimethyl-formamide and water mol-ecules are present in the crystal, the contributions of which were omitted from refinement. Inter-molecular C-H?N hydrogen bonding is observed.

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.

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.
