The title compound, [Fe(C13H11N4)2], was synthesized starting from 1,1′-ferrocenedicarboxylic acid in a three-step reaction sequence. The dicarboxylic acid was reduced to 1,1′-ferrocenedimethanol using LiAlH4 and subsequently converted to 1,1′-bis(azidomethyl)ferrocene in the presence of NaN3. The diazide was treated with 2-ethynylpyridine under `click' conditions to give the title compound in 75% yield. The FeII center lies on an inversion center in the crystal. The two pyridyltriazole wings are oriented in an anti conformation and positioned exo from the FeII center. In the solid state, the molecules interact by C—H...N, C—H...π, and π–π interactions. The complexation of the ligand with [Cu(CH3CN)4](PF6) gives a tetranuclear dimeric complex.

Form Part

The title compound, {[Zn4(C8H4O4)3(OH)2(C12H6N2O2)2]·2H2O}n, has been prepared hydrothermally by the reaction of Zn(NO3)2·6H2O with benzene-1,4-dicarboxylic acid (H2bdc) and 1,10-phenanthroline-5,6-dione (pdon) in H2O. In the crystal structure, a tetranuclear Zn4(OH)2fragment is located on a crystallographic inversion centre which relates two subunits, each containing a [ZnN2O4] octahedron and a [ZnO4] tetrahedron bridged by a μ3-OH group. The pdon ligand chelates to zinc through its two N atoms to form part of the [ZnN2O4] octahedron. The two crystallographically independent bdc2−ligands are fully deprotonated and adopt μ3-κO:κO′:κO′′ and μ4-κO:κO′:κO′′:κO′′′ coordination modes, bridging three or four ZnIIcations, respectively, from two Zn4(OH)2units. The Zn4(OH)2fragment connects six neighbouring tetranuclear units through four μ3-bdc2−and two μ4-bdc2−ligands, forming a three-dimensional framework with uninodal 6-connected α-Po topology, in which the tetranuclear Zn4(OH)2units are considered as 6-connected nodes and the bdc2−ligands act as linkers. The uncoordinated water molecules are located on opposite sides of the Zn4(OH)2unit and are connected to it through hydrogen-bonding interactions involving hydroxide and carboxylate groups. The structure is further stabilized by extensive π–π interactions between the pdon and μ4-bdc2−ligands.

Uv Light Irradiation

The title compound [systematic name: 2-oxo-N,2-diphenyl-N-(propan-2-yl)acetamide], C17H17NO2, was synthesized and its photoreactive properties in the crystalline state were investigated. In the molecule, the carbonyl group attached to the phenyl ring adopts an s-trans configuration with respect to the isopropyl group. Moreover, the distance between the C atom of the carbonyl group and the N-bound C atom of the isopropyl group is 3.845 (2) Å, which is much longer than 3.2 Å, the threshold for photoreactions to take place in the molecule. As a result, the crystal did not photoreact upon UV light irradiation. In the crystal, the molecules are linked via weak intermolecular C—H...O hydrogen bonds, forming a layer structure parallel to the ab plane.

In the title compound, C14H17N3O5S, the five-membered ring is essentially planar. The substituents at the nitrogen atoms subtend a C—N—N—S torsion angle of −95.52 (6)°. The amino group forms an intramolecular hydrogen bond to a sulfonyl oxygen atom; two intermolecular hydrogen bonds from the amino group, to the other S=O group and to the oxo substituent, form a layer structure parallel to the ab plane. The structure determination confirms that the title compound is N- rather than O-alkylated.
