Abstract:
Bis(pyridine-2,6-dimethanol-N,O,O')cobalt(II) disaccharinate dihydrate, [Co(C7H9NO2)2](C7H4NO3S)2*2H2O, (I), and bis(pyridine-2,6-dimethanol-N,O,O')copper(II) disaccharinate dihydrate, [Cu(C7H9NO2)2](C7H4NO3S)2*2H2O, (II), collectively [M(dmpy)2](sac)2*2H2O (where M is Co(II) or Cu(II), sac is the saccharinate anion and dmpy is pyridine-2,6-dimethanol), are isostructural. The [M(dmpy)2]2+ cations exhibit distorted octahedral geometry in which the two neutral dmpy species act as tripodal N,O,O'-tridentate ligands. The crystal packing is determined by hydrogen bonding, as well as by weak pyridine-saccharinate pi-pi-stacking interactions.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
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.
π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...
