Presence of polarization bonds in some copper(II) complexes was written by Hall, D.;McKinnon, A. J.;Waters, J. M.;Waters, T. N.. And the article was included in Nature (London, United Kingdom) in 1964.SDS of cas: 1122-71-0 This article mentions the following:
The structures of bis(N-methyl-2-hydroxy-1-naphthaldiminato)copper(II) (I) and a second crystal modification of bis(salicylaldehydrato)copper(II) (II) were determined by space group requirements and 3-dimensional Fourier syntheses. The space group of I is P21/n with Z = 2, a 3.86, b 19.55, c 12.57, and β = 91.1°. II belongs to space group P21/c with Z = 2, a 11.75, b 4.00, c 12.42, and β = 90.3°. I and II are essentially sq. planar but the mols. pack so that there is an axial approach of 2.94 and 3.15 A., resp., to the hydroxy O of neighboring mols. and thus a deviation from overall mol. planarity. Within one mol. the 2 ligands are individually planar but mean planes through them are separated by 1.16 A. and 0.36 A. The distortions indicate that definite weak interactions exist; polarization bonding is suggested. The polarization bonds can involve different regions of the ligand, being to the O of the chelated ring in II and to a C of the benzene ring in the previously reported modification of II. In the experiment, the researchers used many compounds, for example, 6-Methyl-2-pyridinemethanol (cas: 1122-71-0SDS of cas: 1122-71-0).
6-Methyl-2-pyridinemethanol (cas: 1122-71-0) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.SDS of cas: 1122-71-0
