RESUMO
The title compound, C(27)H(39)N(3)O(2)·H(2)O, is a chiral pyridine-2,6-dicarboxamide derivative including cis-myrtanyl groups as amine substituents. The pyridine-2,6-dicarboxamide core approximates C(2) point symmetry and a solvent water mol-ecule lies on the pseudo-twofold axis. The water mol-ecule serves both as acceptor and donor for efficient hydrogen bonds involving N-H and C=O functional groups as donor and acceptor groups, respectively. As a result, each water mol-ecule in the crystal structure is tetra-hedrally bonded to three symmetry-related mol-ecules, forming a three-dimensional supra-molecular network. Such an arrangement is a common feature found in the majority of X-ray-characterized sym-metrically substituted pyridine-2,6-dicarboxamide derivatives.
