摘要

In a previous crystallographic study of some N-arylpyrimidinones 1, we noted that:(1) C–H⋯ O hydrogen bonds connect molecules in a linear array;(2) the charge transfer axis of the chromophore is aligned with the main symmetry operator of point groups 2 or m at ca. 57°, a value that is close to the ideal angle of 54.74°;(3) the methyl and chloro derivatives are isostructural. In this paper, we report the characterisation of chloride and nitrate salt ...
