Centrosymmetric Dimers

In the title compound, [ReBr(C13H10N4)(CO)3], the ReIatom has a distorted octahedral coordination environment. Two N atoms of the 5-phenyl-3-(pyridin-2-yl)-1H-1,2,4-triazole ligand and two of the three carbonyl groups occupy the equatorial plane of the complex, with the third carbonyl ligand and the bromide ligand in the axial positions. The three carbonyl ligands are arranged in afacconfiguration around the ReIatom. Mutual N—H...Br hydrogen bonds arrange molecules into centrosymmetric dimers. Additional stabilization within the crystal structure is provided by C—H...O and C—H...Br hydrogen bonds, as well as by slipped π–π stacking interactions [centroid-to-centroid distance = 3.785 (5) Å], defining a three-dimensional network.

In the title compound, C18H17NO4, the dihedral angle between the phenyl ring and the fused six-membered ring is 77.65 (4)°. The conformation of the molecule is determined in part by an intramolecular N—H...O hydrogen bond between the amino H atom and the carbonyl O atom, forming anS(6) motif. In the crystal, molecules are linked into N—H...O hydrogen-bonded inversion dimers which are then connected into chains along [001], forming a two-dimensional network parallel to (100)viaO—H...O hydrogen bonds. C—H...O interactions further contribute to the crystal stability. The ethyl group is disordered over two sets of sites in a 0.801 (5):0.199 (5) ratio.

In the crystal structure of the title organic proton-transfer complex, 2C12H11N2 +·C7H4O5S2−·3H2O, the cations form one-dimensional chains via intermolecular N—H...N hydrogen bonds and these chains, in turn, form a two-dimensional network through π–π stacking interactions. In addition, the anions and water molecules are connected into a two-dimensional hydrogen-bonded network through intermolecular O—H...O hydrogen bonds. The two motifs result in sheets of cations and anions stacked alternately.
