Overlay diagram of conformations of the title compound. The N1-, N4-, N7- and N10-containing molecules determined in the present study are shown in red, pink, blue and aqua, respectively; the N1-, N7- and N10-containing molecules were inverted for a better fit. The green and yellow images correspond to the unique molecules in the known polymorph and the black image corresponds to the geometry-optimized structure. |
