Crystal structure, Hirshfeld surface analysis and corrosion inhibition study of 3,6-bis(pyridin-2-yl)-4-{[(3aS,5S,5aR,8aR,8bS)-2,2,7,7-tetramethyltetra-hydro-5H-bis[1,3]dioxolo[4,5-b:4',5'-d]pyran-5-yl)-methoxy]methyl}pyridazine monohydrate

In the title compound, C₂₇H₃₀N₄O₆H₂O, the two dioxolo rings are in envelope conformations, while the pyran ring is in a twisted-boat conformation. The pyradizine ring is oriented at dihedral angles of 9.23 (6) and 12.98 (9) with respect to the pyridine rings, while the dihedral angle between the two pyridine rings is 13.45 (10). In the crystal, O-H_water O_pyran, O-H_water O_{methoxymethyl} and O-H_water N_pyridazine hydrogen bonds link the molecules into chains along [010]. In addition, weak C-H_dioxolo O_dioxolo hydrogen bonds and a weak C-H_{methoxymethyl} interaction complete the three-dimensional structure. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H H (55.7%), H C/ C H (14.6%), H O/O H (14.5%) and H N/N H (9.6%) interactions. Hydrogen-bonding and van der Waals interactions are the dominant interactions in the crystal packing. Electrochemical measurements are also reported.
