Figure 2 Overlay diagram of the two independent molecules of (I) and the polymorph of (I). The molecules have been aligned so that nitrile-N atom closest to the partially saturated ring, amino-N and the C atom diagonally opposite to the amino-N\ atom have been superimposed. Colour code: red = N1-molecule of (I), green = N4-molecule (inverted) of (I) and blue = polymorph of (I). |
