The title compound, C(19)H(15)Cl(2)N(3)O(2), was obtained by a one-step cyclo-condensation of 2-amino-1-(4-chloro-phen-yl)imidazoline with diethyl (2-chloro-benz-yl)malonate under basic conditions. In the crystalline state, the mol-ecule exists as the 7-hy-droxy-5-oxo tautomer. The dihedral angles between the fused imidazopyrimidine and aromatic chloro-phenyl and chloro-benzyl rings are 14.2 (1...
The asymmetric unit of the title co-crystalline 1:2 adduct, C(12)H(12)N(2)O(2)·2C(6)H(3)N(3)O(6), contains two independent mol-ecules of bis-(4-amino-phen-yl) sulfone (the drug Dapsone) and four mol-ecules of 1,3,5-trinitro-benzene and is extended into a two-dimensional hydrogen-bonded network structure through amino N-H⋯O hydrogen-bonding associations with nitro O-atom acceptors. In the two in...
THE TITLE COMPOUND [SYSTEMATIC NAME: 4-(2,2-diphenyl-2-prop-oxyacet-oxy)-1-methyl-piperidin-1-ium picrate], C(23)H(30)NO(3) (+)·C(6)H(2)N(3)O(7) (-), crystallizes as a salt with one cation-anion (propiverinium picrate) pair in the asymmetric unit. A significant number of conformational changes are observed between the crystalline environment of this cation-anion salt and that of a density funct...
