Abstract:
The title compound, [Zn(C8H5O4)2(C10H8N2)2], was obtained by the hydrothermal reaction of ZnSO4.7H2O with phthalic acid (H2pht) and 4,4'-bipyridine (4,4'-bipy). Crystallographic analysis shows that it has a one-dimensional double-chain structure via hydrogen-bonding interactions. Each Zn(II) atom, adopting a distorted tetrahedral geometry, is coordinated by two N atoms from two 4,4'-bipy ligands, with Zn-N distances of 2.054 (4) and 2.104 (4) A, and by two O atoms from symmetry-related Hpht- ligands, with Zn-O distances of 1.921 (4) and 2.019 (4) A.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
