Figure 20
A scatterplot of N—H⋯O angles against N⋯O distances in intermolecular N—H⋯O hydrogen bonds for phosphoric triamides with a C(O)—NH—P(O) fragment found in the CSD and in four title structures. All contacts with N⋯O ≤ 3.10 Å are included. The black and red squares denote the two-centered and three-centered hydrogen bonds, respectively. The yellow square which lies just above the head of the central arrow denotes one intermolecular N—H⋯O hydrogen bond in a singular example of a four-centered hydrogen bond which contains two intramolecular and one intermolecular N—H⋯O hydrogen bonds.
