Title Molecule

In the title molecule, C20H19FN4O3S, the heterocyclic thiazine ring adopts a half-chair conformation with the S atom displaced by 0.668 (4) Å from the mean plane formed by the remaining ring atoms. The mean planes of the benzene and pyrazole rings are inclined with respect to each other at a dihedral angle of 17.4 (3)°. The acetamide chain (O/N/C/C/C) linking the pyrazole and 2-fluorobenzyl rings is essentially planar (r.m.s. deviation = 0.030 Å) and forms dihedral angles with the mean planes of these rings of 78.8 (2) and 78.89 (14)°, respectively. The crystal structure is stabilized by N—H...O and C—H...O hydrogen-bonding interactions, resulting in a six-membered ring with anR21(6) motif, while C—H...O and C—H...F hydrogen-bonding interactions result in chains of molecules lying along thecaxis in a zigzag fashion.

In the title compound, C29H37N5O4S2, two arms substituted with dansyl derivatives are connected to a central tertiary amine, where the dihedral angle between the planes of two dansyl units is 56.39 (4)°. Each arm contains a sulfonamide functional group and both N—H groups in the compound are pointed to the same side. The central part of the molecule is disordered over three sets of sites with a refined occupancy ratio of 0.547 (4):0.328 (4):0.125 (3). No intramolecular π–π or hydrogen-bonding interactions are observed. In the crystal, molecules are linkedviapairs of N—H...O interactions involving the same acceptor atom, forming inversion dimers. In addition, C—H...O interactions exist between molecules, providing further stabilization of dimers.

The asymmetric unit of the title coordination polymer, [Co(C9H4N2O4)(C2H4N4)] n or [Co(L 1)(L 2)] n , consists of one crystallographically independent Co2+ centre, one L 1 2− ligand and one L 2 ligand (L 1 = 1H-benzimidazole-5,6-dicarboxylic acid, L 2 = 3-amino-1,2,4-triazole). The Co2+ centre is coordinated by two carboxylato-O atoms from two independent L 1 2− ligands and two nitrogen atoms from L 2 and another L 1 ligand. Thus, the metal center adopts a four-coordinate mode, forming a tetrahedral geometry. Interestingly, through the combination of two L 1 2−, two L 2 ligands and two Co2+ ions, a basic repeating unit is constructed, resulting in the formation of a one-dimensional straight chain structure. These chains are further expanded to the final three-dimensional framework via N—H...O hydrogen-bonding interactions.

The furan and one of the phenanthrene groups are fused in an almost coplanar arrangement [dihedral angle = 5.14 (8)°] and the furan unit makes dihedral angles of 70.27 (11) and 57.58 (8)° with the planes of the phenyl and the second phenanthrene group, respectively. In the crystal, neighbouring molecules are connectedviatwo intermolecular hydrogen-bonding interactions (O—H...O and C—H...O) towards the carbonyl O atom with donor–acceptor distances of 2.824 (2) and 3.277 (3) Å, creating an inversion dimer. A non-classical C—H...Cl interaction [3.564 (2) Å] and three C—H...π interactions, with C...π distances of 3.709 (3), 3.745 (2) and 3.628 (3) Å, connect the molecules, forming a three-dimensional supramolecular architecture in the solid state.

Abstract The complexes [Zn(dpa)MoO4] (1) and [Zn(dpa)MoO4]·0.5H2O (20.5H2O) (dpa = 2,2'-dipyrid- ylamine) were synthesized hydrothermally. Single crystal structure analyses indicate that 1 and 2 are conformational isomers. They both consist of binuclear units of edge-sharing {ZnN2O3} trigonal bipyramids bridged by pairs of bidentate briding {MoO4}2- anions into a one-dimensional ribbon, but their orientations of the terminal O atoms of the {MoO4}2- anions are different. In 1 and 2, the ribbon-like chains are connected into a 2D network via hydrogen bonding interactions between the central N-H portions of the dpa molecules and the terminal O atoms of {MoO4} tetrahedra. For 2, in addition, the hydrogen bonding interactions between the crystal water molecules and the terminal O atoms of {MoO4} tetrahedra join the 2D layers into a 3D architecture. They play an important role not only in constructing the 3D architecture, but also in the conformational stability.
