- W4207013630 abstract "The structure of 3-(3,4-dimethoxyphenylethylamino)-methylidene-1,2,3,9-tetrahydropyrrolo[2,1-b]-quinazolin-9-one hydrochloride was determined by single-crystal X-ray diffraction at 100 K. The compound crystallizes in the monoclinic space group Cc, with a = 4.7149(18), b = 30.075(12), c = 14.199(6) Å, β = 91.852(8)°, Z = 4, V = 2012.4(14) Å3. The crystallographic study revealed E configuration of the C11 = N9′ bond. Electrostatic interactions between the organic cation and the chloride anion and classical N-H…Cl hydrogen bonds stabilize this salt. A Hirshfeld surface analysis revealed that H···H, H···C/C···H, and H···O/O···H represent the most prominent Van-der-Waals contacts. For the neutral parent molecule, nuclear magnetic resonance spectroscopy in deuterated chloroform solution showed that two tautomeric forms coexist in 3:1 ratio." @default.
