Abstract
Two new addition compounds of the optically non-linear molecule 4-nitr opyridine N-oxide (NPO) have been synthesized and characterized: bis(4 -nitropyridine N-oxide)silver nitrate and bis(4-nitropyridine N-oxide) cobalt nitrate tetrahydrate. Their structural features are described a nd compared, in particular the arrangement of the NPO molecules, the t ype of linkage in the inorganic entities (the cationic polyhedra and t he nitrate anions) which make up the host matrice for the organic mole cules and the hydrogen-bonding scheme contributing to the packing cohe sion. Certain characteristics of both these centrosymmetric structures are also discussed with respect to some non-linear optical NPO deriva tives.
