Partial views of the molecular packings of 1 (left) and 2 (right) formed via classical N−H…O=P hydrogen bond. The 1D linear arrangement along the b (for 1) and c (for 2) axis are formed. For 1, the 1D chain is produced by linking of three symmetry‐independent molecules shown by different colors (red, blue and green). The O=P−NH segments involved in hydrogen bonding are shown as ‘ball and sticks’.
