Crystal structure of methyl 3-(3-fluorophenyl)-1-methyl-1,3a,4,9b-tetrahydro-3H-thiochromeno[4,3-c]isoxazole-3a-carboxylate
In the title compound, C19H18FNO3S, the five-membered oxazolidine ring adopts an envelope conformation with the methine C atom of the fused bond as the flap. Its mean plane is oriented at a dihedral angle of 50.38 (1)° with respect to the fluoro-phenyl ring. The six-membered thio-pyran ring has a half-chair conformation and its mean plane is almost coplanar with the fused benzene ring, making a...
متن کامل1-Butyl-1-chloro-3-methyl-3H-2,1λ4-benzoxatellurole: crystal structure and Hirshfeld analysis
Two independent mol-ecules comprise the asymmetric unit in the title benzoxatellurole compound, C12H17ClOTe. The mol-ecules, with the same chirality at the methine C atom, are connected into a loosely associated dimer by Te⋯O inter-actions, leading to a {⋯Te-O}2 core. The resultant C2ClO2 donor set approximates a square pyramid with the lone pair of electrons projected to occupy a position tran...
متن کاملCrystal structure of 1-benzyl-3-methyl-1H-imidazolium hexafluoridophosphate
In the title salt, C11H13N2 (+)·PF6 (-), the dihedral angle between the planes of the imidazole and benzene rings is 84.72 (4)°. In the crystal, C-H⋯F inter-actions connect the cation and anion pairs into a three-dimensional network. Weak π-π inter-actions are observed between the imidazolium ring and the aromatic benzene ring of an adjacent mol-ecule with C⋯C and C⋯N distances ranging from 3.3...
متن کاملCrystal structure of 1-methyl-3-[2,2,2-trifluoro-1-(1-methyl-1H-indol-3-yl)-1-phenylethyl]-1H-indole
The title compound, C26H21F3N2, was prepared by the palladium-catalysed reaction of (2,2,2-tri-fluoro-eth-yl)benzene with 1-methyl-1H-indole. The dihedral angle between the planes of the indole-ring systems is 52.13 (6)° and the N-methyl groups point away from each other. Three short intra-molecular C-H⋯F contacts are observed.
متن کاملrac-Methyl 3-(2-methoxyphenyl)-3a,4-dihydro-3H-chromeno[4,3-c]isoxazole-3a-carboxylate
The title compound, C19H17NO5, comprising two stereogenic C atoms of the same configuration, crystallizes in a centrosymmetric space group as a racemate. The pyran ring adopts a half-chair conformation, while the isoxazole ring adopts an envelope conformation with the C atom bonded to the meth-oxy-phenyl group as the flap. The dihedral angle between the mean plane of the pyran ring and the adja...
