چکیده
The title compound, C(18)H(14)N(4)O(2), was found as a by-product in the nitro-aldol reaction between 2-(nitro-meth-yl)pyridine and N-(pyridin-2-ylmethyl-idene)methane-amine. Its two stereogenic centers give rise to four stereoisomers of which only the anti isomers are found in this crystal structure.

Synthesis of 1,4-Diamino-2,3-di(2-pyridyl)butane and its Dinuclear Zinc(II) Chloride Complex
In a Henry-type reaction nitromethane reacts with N-(2-pyridylmethylidene)-methylamine (1) yielding 1-methylamino-1-(2-pyridyl)-2-nitromethane (2) in nearly quantitative yield. This orange compound decomposes slowly in an inert gas atmosphere and fast in contact with air. Therefore 2 has to be stored at −78 ◦C as a methanol solution. Reduction of 2 with hydrogen in the presence of a Pd/C cataly...

The Pt(II) ion in the title complex, [PtBr(2)(C(14)H(10)N(4))], has a slightly distorted square-planar environment defined by the two pyridyl N atoms of the chelating 2,3-di-2-pyridyl-pyrazine ligand and two bromide anions. In the crystal, the pyridyl rings are considerably inclined to the least-squares plane of the PtBr(2)N(2) unit [maximum deviation = 0.064 (2) Å] with dihedral angles of 65.2...
