Bis(4-meth-oxy-3,4-di-hydro-quinazolin-1-ium) chloranilate.

ABSTRACT: IN THE TITLE COMPOUND [SYSTEMATIC NAME: bis-(4-meth-oxy-3,4-di-hydro-quinazolin-1-ium) 2,5-di-chloro-3,6-dioxo-cyclo-hexa-1,4-diene-1,4-diolate], 2C9H11N2O(+)·C6Cl2O4 (2-), the chloranil-ate anion lies about an inversion center. The 4-meth-oxy-3,4-di-hydro-quinazolin-1-ium cations are linked on both sides of the anion via bifurcated N-H?(O,O) and weak C-H?O hydrogen bonds, giving a centrosymmetric 2:1 aggregate. The 2:1 aggregates are linked by another N-H?O hydrogen bond into a tape running along [1-10]. The tapes are further linked by a C-H?O hydrogen bond into a layer parallel to the ab plane.

(E)-N'-(3,4-Di-meth-oxy-benzyl-idene)nicotinohydrazide monohydrate.

Project description:In the title hydrated compound, C15H15N3O3·H2O, the nicotinohydrazide mol-ecule adopts a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene and pyridine rings is 5.10?(14)°. In the crystal, the solvent water mol-ecule acts as an acceptor, forming an N-H?O hydrogen bond supported by two C-H?O contacts. It also acts as a donor, forming bifurcated O-H?(O,O) and O-H?N hydrogen bonds that combine with the former contacts to form zigzag chains of mol-ecules along the c-axis direction. An additional O-H?O donor contact completes a set of six hydrogen bonds to and from the water mol-ecule and connects it to a third nicotinohydrazide mol-ecule. This latter contact combines with weaker C-H?O hydrogen bonds supported by a C-H?? contact to stack mol-ecules along b in a three-dimensional network.
