摘要
A novel dihydrated form of 2,9-dimethyl-1,10-phenanthroline (neocuproine), C14H12N2. 2H(2)O, is described. The molecule is very similar to that already reported in the literature, the main differences being in the packing. The positioning of the H atoms had a great influence in the convergence of the refinement process, This was performed in C2/m, though there were some suggestions of slight deviations from the crystallographic mirror symmetry.
