Abstract:
The asymmetric unit of the title polymeric compound, [Zn(C8H5O3)2(C4H4N2)(H2O)]n, contains two molecular units. Each unit comprises two 4-formylbenzoate (FB) anions, one pyrazine molecule and one coordinating water molecule; the FB anions act either as bidentate or as monodentate ligands. The O atoms of the bidentately coordinating FB anions are disordered over two positions, and they were refined with fixed occupancy ratios of 0.75:0.25 and 0.70:0.30, respectively. In the ordered monodentately coordinating FB anions, the carboxylate groups are twisted away from the attached benzene rings (Ban

Abstract:
In the title compound, C16H10ClNO2, the dihedral angle between the quinoline ring system and the benzene ring is 14.7 (5)°. The carboxylate group is twisted from the mean planes of the quinoline ring system and the benzene ring by 17.7 (5) and 32.1 (4)°, respectively. In the crystal, inversion dimers are formed with the molecules linked by pairs of weak C—H...O interactions arising from an activated aromatic C atom adjacent to the C—Cl bond, generatingR22(14) loops.

The common feature of these salts is the presence of the 2-amino-4-nitrobenzoate anion, which exhibit non-chemically significant variations in the conformational relationships between the carboxylate and nitro groups, and between these and the benzene rings they are connected to. The number of ammonium-N—H H atoms in the cations increases from one to three in (I) to (III), respectively, and this variation significantly influenc

Coordination polymers constructed from metal ions and organic ligands have attracted considerable attention owing to their diverse structural topologies and potential applications.

Abstract:
In the title compound, C18H18O6, the benzene rings are coplanar due to the centrosymmetric nature of the molecule, with an inversion centre located at the midpoint of the C—C bond between the two rings. Consequently, the methyl carboxylate substituents are oriented in atransfashion with regards to the bond between the benzene rings. The methyl carboxylate and methoxy substituents are rotated slightly out of plane relative to their parent benzene rings, with dihedral and torsion angles of 18.52 (8) and −5.22 (15)°, respectively.

Abstract:
This chapter discusses bonding in extended systems and relates this to conjugation. It uses the reaction of benzene bonding with all of the carbons as a reference. The chapter also refers to the structure of butadiene and propenal as examples showing the case of four p orbitals in a row. Amides, allyl anion and carboxylate anion are used to show cases where three p orbitals are in a row. In addition, the chapter discusses the chemical consequences of carbonyl compound reactions. It concludes by examining the stabilization of negative charges following the conjugation of bonds.
