Severance, Rachel C.; Ellsworth, Joe; Smith, Mark D.; Kelley, Jennifer; Peterson, LeRoy Jr.; zur Loye, Hans-Conrad published their research in Journal of Chemical Crystallography on December 31 ,2010. The article was titled 《Synthesis and Crystal Structure of the Coordination Complex Cu(ppca’)2(H2O)2 (ppca’ = 3,4′-Bipyridine-6-Carboxylic Acid)》.Formula: C11H8N2O2 The article contains the following contents:
The coordination complex Cu(ppca’)2(H2O)2 (1) was synthesized hydrothermally using the ligand 3,4′-bipyridine-6-carboxylic acid (ppca’). Complex 1 consists of pseudo-octahedral copper(II) units hydrogen bonded into a three-dimensional network that crystallizes in the monoclinic P21/n space group. In complex 1, a 5.3429(4), b 29.343(2), c 6.7940(5) Å, and β 110.635(2)°. The experimental part of the paper was very detailed, including the reaction process of [3,4′-Bipyridine]-6-carboxylic acid(cas: 1214363-66-2Formula: C11H8N2O2)
[3,4′-Bipyridine]-6-carboxylic acid(cas: 1214363-66-2) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. Formula: C11H8N2O2 Pyridine has a conjugated system of six π electrons that are delocalized over the ring.
