Ethyl 3-oxo-2-(2-phenylhydrazinylidene)butanoate: a re-determination
The previous crystallographic studies [Wang et al. (2005 ▶). Huaxue Yanjiu16, 29-32; Wang et al. (2007 ▶). Youji Huaxue, 27, 524] of the title compound, C(12)H(14)N(2)O(3), gave only the unit-cell dimensions and an R factor with no other details available: the full structure is presented here. The eth-oxy group is disordered over two orientations with refined occupancies of 0.642 (15):0.358 (15...
متن کامل(Z)-Ethyl 2-oxo-3-(1,2-dihydroquinolin-2-ylidene)propanoate
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...
متن کامل2-Oxo-2-(2-oxo-2H-chromen-3-yl)ethyl diethyldithiocarbamate
In the title compound, C16H17NO3S2, the dihedral angles between the O/C/C/S group and the 2H-chromene ring system and the thio-carbamate group are 14.46 (9) and 83.30 (9)°, respectively. The bond-angle sum at the N atom is 360.0°. One of the methyl C atoms lies above the thio-carbamate plane and one lies below it [deviations = 1.264 (3) and -1.147 (3) Å, respectively]. In the crystal, inversion...
متن کامل2-Oxo-2-(2-oxo-2H-chromen-3-yl)ethyl pyrrolidine-1-carbodithioate
There are two independent mol-ecules in the asymmetric unit of the title compound, C16H15NO3S2, in which the pyrrolidine rings adopt envelope conformations, with a methyl-ene C atom as the flap. The dihedral angles betweeen the near-planar 2H-chromene ring systems [maximum deviations = 0.0167 (20) and 0.0136 (19) Å] and the pyrrolidine rings (all atoms) are 83.83 (11) and 82.43 (11)°. In the cr...
متن کاملEthyl N-(2-benzoyl-3-oxo-3-phenylpropanoyl)carbamate
In the title compound, C(19)H(17)NO(5), the dihedral angle between the phenyl groups is 79.55 (15)°. The terminal eth-oxy group is disordered over two orientations in a 0.873 (6):0.127 (6) ratio. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds into [001] chains which incorporate R(1) (2)(6) loops. A very weak C-H⋯π contact also occurs.
