A crystal packing diagram for (II). H atoms bound to C atoms have been omitted for clarity. The P=O⋯H—Namide (marked a) and C=O⋯H—NC(O)NHP(O) (marked b) hydrogen bonds are shown. (Colour key for the electronic version of the paper: red and black dashed lines, respectively; the atomic colour scheme is the same as for Fig. 7.) |
