1′-Acetyl-3-phenyl-6-oxa-4-thia-2-azaspiro[bicyclo[3.2.0]hept-2-ene-7,3′-indolin]-2′-one
In the title indoline compound, C(19)H(14)N(2)O(3)S, the pyrrolidine ring adopts an envelope conformation with the four-connected (spiro) C atom as the flap [displacement = 0.148 (3) Å]. The mean plane formed through the indoline unit is inclined at dihedral angles of 89.92 (16) and 59.54 (12)° with the thia-zole and phenyl rings, respectively; the dihedral angle between the latter rings is 9.5...
متن کامل7-Benzenesulfonamido-3-ethenyl-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid methanol solvate
In the title compound, C(15)H(14)N(2)O(5)S(2)·CH(4)O, the six-membered ring fused to the β-lactam unit adopts a twisted conformation. In the crystal structure, the component mol-ecules are linked into a three-dimensional framework through inter-molecular N-H⋯S, N-H⋯O and O-H⋯O hydrogen bonds and C-H⋯O contacts.
متن کامل7-Benzenesulfonamido-3-methyl-8-oxo-5-thia-1-azabicyclo[4.2.0]octa-2-ene-2-carboxylic acid monohydrate
In the title compound, C(14)H(14)N(2)O(5)S(2)·H(2)O, the six-membered ring fused to the β-lactam unit has a twisted conformation. Weak intra-molecular N-H⋯S and C-H⋯O inter-actions occur. Inter-molecular C-H⋯S, N-H⋯O, C-H⋯O and O-H⋯O hydrogen-bonding inter-actions stabilize the crystal structure, forming a three-dimensional network. Weak C-H⋯π inter-actions are also present.
متن کامل1-[(Z)-2-Butyltellanyl-1-chloroethenyl]cyclohex-1-ene
The Te(II) atom in the title mol-ecule, C(12)H(19)ClTe, is coordinated in a V-shaped geometry by C atoms derived from the disparate organic substituents. A short intramolecular C-H⋯Cl contact occurs owing to the proximity of the ethene bond in the six-membered ring to the Cl atom. In the crystal, mol-ecules assemble into layers parallel to the ac plane, with the closest inter-actions between th...
متن کامل3-(2-Ethoxyphenyl)-1-(3-nitrophenyl)triaz-1-ene
The title compound, C(14)H(14)N(4)O(3), exhibits a trans geometry about the N=N double bond in the triazene unit. The mol-ecule is approximately planar (r.m.s. deviation = 0.044 Å for all non-H atoms). An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, C-H⋯N hydrogen bonds lead to the formation of dimers which are, in turn, connected to each other by C-H⋯O hydrogen bonds, forming in...
