Mol-ecules of the title macrocycle, C(36)H(22)N(4)O(4), are located on an inversion center. The porphyrin ring shows a wave-like conformation with adjacent pyrrole rings tilted above the porphyrin plane and the inter-porphyrin distance is 3.584 (3) Å. The dihedral angles between the meso-furyl groups and the porphyrin plane are 38.87 (7) and 48.29 (7)°; these are much smaller than those observe...

In the title compound {systematic name: methyl 1-[12-oxo-10-(3,4,5-trimethoxy-phen-yl)-4,6,13-trioxa-tetra-cyclo-[7.7.0.0(3,7).0(11,15)]hexa-deca-1,3(7),8-trien-16-yl]-1H-1,2,3-triazole-4-carboxyl-ate dichloro-methane solvate}, C(26)H(25)N(3)O(9)·CH(2)Cl(2), the tetra-hydro-furan ring and the six-membered ring fused to it both display envelope conformations.

In the title compound, [Sn(C(6)H(5))(3)(C(14)H(9)N(2)O(4))], the Sn atom has a distorted tetra-hedral geometry with one of the carboxyl-ate O atoms and the C atoms from three phenyl groups. The other carboxyl-ate O atom of the benzoate ligand inter-acts weakly with the Sn atom, with an Sn⋯O distance of 2.790 (2) Å, which causes a distortion of the tetra-hedral coordination geometry.

The title dinuclear titanocene, [Ti(2)(C(8)H(9)O)(C(18)H(25)Si)(2)Cl(3)O], contains one Ti atom tetra-hedrally coordinated by two Cl atoms, a bridging O atom and the substituted cyclo-penta-dienyl ligand, and another Ti atom tetra-hedrally coordinated by a Cl atom, a bridging O atom, the 2,6-dimethyl-phenolate ligand and the substituted cyclo-penta-dienyl ligand. The bridging O atom lies on a t...

Assistant dopants with reduced Dexter energy transfer rates were designed by replacing the donor moiety of 2,3,5,6-tetra(9 H -carbazol-9-yl)terephthalonitrile (4CzTPN) 5 -benzo[4,5]thieno[3,2- c ]carbazole (BTCz).

The asymmetric unit of the title compound, [Mg(H(2)O)(6)](C(9)H(7)N(4)O(2)S)(2), contains one-half of a [Mg(H(2)O)(6)](2+) cation ( symmetry) and one uncoordinated 2-[(1-phenyl-1H-tetra-zol-5-yl)sulfan-yl]acetate anion. The Mg(II) cation is coordinated by six water mol-ecules, exhibiting a slightly distorted octa-hedral coordination. A two-dimensional network parallel to (001) is formed via ext...

In the title mol-ecule, C(25)H(19)N(3)O(3)S(3), the tetra-hydro-pyridine ring adopts a half-chair conformation. The dihedral angle between the least-squares plane through the tetra-hydro-pyridine ring and two thio-phene and two benzene rings are 6.25 (9), 89.49 (9), 76.43 (9) and 84.93 (8)°, respectively, while the dihedral angle between the 1,3,4-oxadiazole and tetra-hydro-pyridine rings is 81...

In the title compound, {[Cu(C(9)H(15)N(13))(2)](ClO(4))(2)}(n), the Cu(2+) cation lies on an inversion center and is coordinated by the tetra-zole N(4) atoms of six symmetry-equivalent tris-[2-(1H-tetra-zol-1-yl)eth-yl]amine ligands (t(3)z) in the form of a Jahn-Teller-distorted octa-hedron with Cu-N bond distances of 2.0210 (8), 2.0259 (8) and 2.4098 (8) Å. The tertiary amine N atom is stereoc...

The title polymer, [Cu(2)Cl(2)(C(9)H(9)N(5))(2)](n), has been prepared by the solvothermal treatment of CuCl with 4-(2-allyl-2H-tetra-zol-5-yl)pyridine. The crystal structure shows that the title compound is a homometallic Cu(I)-olefin coordination polymer, in which the Cu(2)Cl(2) nodes are bridged by two olefin ligands. The asymmetric unit contains one-half of the monomer, the complete monomer...
