Abstract:
In the cation of the title compound, [Co(H(2)O)(6)](C(13)H(10)NO(4)S)(2), the Co atom lies on a centre of symmetry and its coordination geometry is octahedral. The crystal structure is stabilized by water-anion O-H⋯O hydrogen bonds. An intra-molecular O-H⋯N hydrogen bond occurs in the anion.

Synthesis of an Oxygen-Carrying Cobalt(II) Complex
Bioinorganic chemistry is the field of study that investigates the role that metals play in biology. Approximately half of all proteins contain metals and it is estimated that up to one third of all proteins rely on metal-containing active sites to function. Proteins that feature metals, called metalloproteins, play a vital role in a variety of cell functions that are necessary for life. Metalloproteins...

Criteria for Aromaticity and the Hückel 4n + 2 Rule
For the first time, Eric Hückel, a German chemical physicist, derived a set of structural features for a compound to be classified as aromatic. This is now known as Hückel’s rule or the 4n +...
