We previously reported the synthesis of some novel disperse dyes based on substituted pyridines
and their derivatives, oxazine, carbooxyanilide and thiocarbamate and evaluated their insecticidal and antifungal activity [18, 19].
The main nitrogen compounds identified were anilines, pyridine
and quinoline compounds.

The asymmetric unit comprises one Co(II) atom, three pyridine
molecules, one 3,5-dichlorosalicylaldehyde-2-amino-4-nitrophenol or 3,5-dibromosalicylaldehyde-2-amino-4-nitrophenol Shiff base, respectively.

In this study, we investigated three aminophosphonate derivatives of pyridine
, including (diphenylphosphoryl) (pyridine-2-yl)methanol ([alpha]-Pyr), (diphenylphosphoryl) (pyridin-3-yl)methanol ([beta]-Pyr), and (diphenylphosphoryl) (pyridin-4-yl)methanol ([gamma]-Pyr) (Table 1 shows molecular structures of these compounds) using surface-enhanced Raman scattering (SERS) technique.
The magnetic moments of 1:1 complexes of bis(O-ethyldithiocarbonato)copper(II) with substituted pyridines
fall in the range 1.81-1.94 B.M (Table 1) which is in agreement with magnetic moment values observed for distorted square pyramidal complexes of copper(II) [8-10].
Three new amino alkyl pyridine
alkaloids, callyspongine A (1), B (2), and C (3) along with two known steroids, 24methylenecholesterol (4) and 24-methylcholesterol (5) were isolated.

The IR spectrum of the ligand has several bands appearing at 3448, 1472, and 1623 [cm.sup.-1] due to phenolic O-H group, pyridine
C=N, and imine CH=N stretching vibrations in the solid state (see Figure S1 in Supplementary Material available online at http://dx.doi.org/10.1155/2014/104046).
