Ethyl 3-(3-ethoxy-2-hydroxybenzylidene)carbazate
In the title compound, C(12)H(16)N(2)O(4), an intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming chains propagating in the [010] direction.
متن کامل(Z)-Ethyl 2-(3-nitrobenzylidene)-3-oxobutanoate
The title mol-ecule, C(13)H(13)NO(5), adopts a Z conformation at the C= C double bond. The eth-oxy atoms of the ethyl ester group are disordered over two orientations in a 3:2 ratio. Weak inter-molecular C-H⋯O hydrogen bonds help to establish the packing.
متن کامل(E)-Ethyl 3-(3-bromophenyl)-2-cyanoacrylate
The title mol-ecule, C(12)H(10)BrNO(2), adopts an E configuration with respect to the C=C bond of the acrylate unit. In the crystal structure, mol-ecules are connected by a pair of inter-molecular C-H⋯O hydrogen bonds, forming a centrosymmetric dimer.
متن کاملEthyl 2-[(3-chlorophenyl)hydrazono]-3-oxobutanoate
The mol-ecule of the title oxobutanoate derivative, C(12)H(13)ClN(2)O(3), adopts a keto-hydrazo tautomeric form and is roughly planar, the angle between the benzene ring and the mean plane through the hydrazone and aliphatic chain being 1.49 (6)°. This planarity is further aided by the formation of an intra-molecular N-H⋯O hydrogen bond which generates an S(6) ring motif. The aromatic ring and ...
متن کاملEthyl 2-(3-benzoylthioureido)acetate
The title compound, C(12)H(14)N(2)O(3)S, adopts a cis-trans geometry of the thio-urea group and is stabilized by intra-molecular hydrogen bonds between the carbonyl O atoms and the H atom of the thio-amide group and by a C-H⋯S interaction. Mol-ecules are linked by two inter-molecular hydrogen bonds (C-H⋯O and N-H⋯O), forming a one-dimensional chain parallel to the c axis.
