Project description:In the title complex, [Zn(C(48)H(36)N(4))]·CH(2)Cl(2), the Zn(II) atom lies on an inversion center and the dichloro-methane solvent mol-ecule is disordered around an inversion center.

[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).

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.

[5,10,15,20-Tetra-kis(4-meth-oxy-phen-yl)porphyrinato]zinc di-chloro-methane disolvate.

Project description:In the title compound, [Zn(C48H36N4O4)]·2CH2Cl2, the Zn(II) ion lies on an inversion center and is coordinated in an almost ideal square-planar geometry. The asymmetric unit also contains one di-chloro-methane solvent mol-ecule.

The packing is characterized by close contacts between the Zn(II) ion and two symmetry-related mol-ecules through the O atoms of a meth-oxy-phenyl group [Zn⋯O = 2.694 (2) Å], forming a two-dimensional network parallel to (100).

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-(μ-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.
