Abstract:
In the title compound, C15H14FNO3S2, the 2H-chromene ring system is close to being planar (r.m.s. deviation = 0.024 Å) and the morpholine ring adopts a chair conformation. The dihedral angle between the 2H-chromene ring system and the morpholine ring (all atoms) is 88.21 (11)°. In the crystal, inversion dimers linked by pairs of very weak C-H⋯F hydrogen bonds generate R 2 (2)(8) loops; C-H⋯O hydrogen bonds connect the dimers into [010] chains. Weak aromatic π-π stacking inter-actions between the pyran rings of the chromene systems [centroid-centroid distance = 3.6940 (16) Å] are also observed.

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
01:07Radicals: Electronic Structure and Geometry
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
01:28Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...

02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
