N,N,N',N'-Tetra-kis(pyridin-4-yl)methane-diamine monohydrate
Abstract:
In the title compound, C(21)H(18)N(6)·H(2)O, two 4,4'-dipyridyl-amine groups are linked by a methyl-ene C atom, which sits on a twofold axis. The lattice water mol-ecule is located slightly off a twofold axis, and is therefore disordered over two positions. In the crystal, the organic mol-ecules and the water mol-ecule are linked by O-H⋯N hydrogen bonds. The organic mol-ecules exhibit extensive offset face-to-face π-π inter-actions to symmetry equivalents [centroid-centroid distances = 3.725 (3) and 4.059 (3) Å].

The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
