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-Tetra­Methyl­Tetra­Hydro-5H-Bis­[1,3]Dioxolo[4,5-B:4′,5′-D]Pyran-5-Yl)Meth­Oxy]Meth­Yl}Pyridazine Monohydrate

Abstract

The title compound is built up by two dioxolo, two pyridine, one pyridazine and one pyran rings. The two dioxolo rings are in envelope conformations, while the pyran ring is in 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, C—Hdioxolo⋯Odioxolo, O—Hwater⋯Opyran, O—Hwater⋯Ometh­oxy­meth­yl and O—Hwater⋯Npyridazine hydrogen bonds link the mol­ecules into a supra­molecular structure. A weak C—Hmeth­oxy­meth­yl⋯π inter­action is also observed., In the title compound, C27H30N4O6·H2O, 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—Hwater⋯Opyran, O—Hwater⋯Ometh­oxy­meth­yl and O—Hwater⋯Npyridazine hydrogen bonds link the mol­ecules into chains along [010]. In addition, weak C—Hdioxolo⋯Odioxolo hydrogen bonds and a weak C—Hmeth­oxy­meth­yl⋯π 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.
