(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.

The title mol-ecule, C(13)H(14)O(3), adopts a Z conformation about the C=C double bond. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds with phenyl -CH atoms functioning as donors and the carbonyl O atom of an ester group as acceptor are observed.

Both independent mol-ecules in the asymmetric unit of the tautomeric title compound, C(14)H(13)NO(3), a synthetic product obtained from 2-lithio-methyl-quinoline and diethyl oxalate, crystallize in the enaminone form with a Z configuration around the double bond. Intra-molecular N-H⋯O hydrogen bonds occur, generating an S(6) graph-set motif. In the crystal, weak inter-molecular C-H⋯O and π-π st...

The crystal structure of the title compound, C9H9N3O2, features N-H⋯N and C-H⋯O inter-actions. The N-H⋯N inter-action generates a chain running along the a axis and the C-H⋯O inter-action generates a chain along the c axis. An intra-molecular C-H⋯O inter-action is also observed.
