Crystal structure of methyl 4-(4-hydroxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate monohydrate
The title hydrate, C13H14N2O4·H2O, crystallizes with two formula units in the asymmetric unit (Z' = 2). The dihedral angles between the planes of the tetra-hydro-pyrimidine ring and the 4-hy-droxy-phenyl ring and ester group are 86.78 (4) and 6.81 (6)°, respectively, for one mol-ecule and 89.35 (4) and 3.02 (4)° for the other. In the crystal, the organic mol-ecules form a dimer, linked by a pai...
متن کاملTricaesium citrate monohydrate, Cs3C6H5O7·H2O: crystal structure and DFT comparison
The crystal structure of tricaesium citrate monohydrate, 3Cs+·C6H5O73-·H2O, has been solved and refined using laboratory X-ray single-crystal diffraction data, and optimized using density functional techniques. This compound is isostructural to the K+ and Rb+ compounds with the same formula. The three independent Cs cations are eight-, eight-, and seven-coordinate, with bond-valence sums of 0.9...
متن کاملCrystal structure of 4-acetamidobenzoic acid monohydrate
In the title compound, C9H9NO3·H2O, the plane of the acetamide group is oriented at 20.52 (8)° with respect to the benzene ring, whereas the plane of the carb-oxy-lic acid group is essentially coplanar with the benzene ring [maximum deviation = 0.033 (1) Å]. In the crystal, classical O-H⋯O and N-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds link the organic mol-ecules and water mol-ecules of...
متن کاملCrystal structure of 4-methyl-N-[2-(piperidin-1-yl)ethyl]benzamide monohydrate
In the title compound, C15H22N2O·H2O, the dihedral angle between the planes of the piperidine and benzene rings is 31.63 (1)°. The piperidine ring adopts a chair conformation. The water solvent mol-ecule is involved in inter-species O-H⋯O, O-H⋯N, N-H⋯O and weak C-H⋯O hydrogen-bonding inter-actions, giving rise to chains extending along [010].
متن کاملMethyl 4-isonicotinamidobenzoate monohydrate
The title compound, C(14)H(12)N(2)O(3)·H(2)O, synthesized by the reaction of methyl 4-amino-benzoate with isonicotinoyl chloride hydro-chloride, is relatively planar, with the pyridine ring being inclined by 7.46 (7)° to the benzene ring. In the crystal, the methyl 4-isonicotinamido-benzoate mol-ecules are inter-linked by water mol-ecules via N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, leading to th...
