Abstract:
The title organometallic complex, [Bi(C(6)H(5))(C(6)H(4)NO(3))(2)(C(3)H(7)NO)], features a Bi(III) atom in a distorted pentagonal-pyramidal coordination by two N,O-donating bidentate 3-hy-droxy-picolinate (3-hpic) ligands, one monodentate dimethyl-formamide (dmf) mol-ecule and one phenyl ring. The C atom of the aryl ligand occupies the apical position of the BiCN(2)O(3) coordination polyhedron, while the equatorial plane is formed by one O atom of the dmf ligand and two sets of N and O atoms from the chelating 3-hpic ligands. Inter-molecular secondary Bi⋯O [3.485 (3) Å] and O-H⋯O hydrogen-bonding inter-actions connect the complexes into a three-dimensional network. Intramolecular O-H⋯O hydrogen bonds are also observed.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...

Preparation of Diols and Pinacol Rearrangement
The reaction begins with transferring a proton from the acid catalyst to one of the hydroxyl groups, producing an oxonium ion.
¹H NMR: Complex Splitting
Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied first.
