Abstract
The title compound crystallizes from acetone with the pyridine rings a rranged at 53 degrees to each other in a trans conformation. There are intramolecular interactions between the alkoxy O atoms of the ester g roups and the C2 atoms of the opposite rings, similar to those observe d in the 3,3'-dinitro analogue. There are no significant intramolecula r interactions between ring N atoms and ester carbonyl C atoms, althou gh similar 1,5 interactions have been observed in other cases.
