Abstract:
In the title compound, C20H23ClN2O2, the cyclo-octene ring has a boat-chair conformation. The ethyl formate moiety is equally disordered over two positions. The dihedral angle between the pyridine and chloro-phenyl rings is 81.33 (13)°. An intra-molecular N-H⋯O hydrogen bond helps to stabilize the mol-ecular conformation. In the crystal, N-H⋯N hydrogen-bonding leads to the formation of dimers with an R 2 2(8) graph-set motif. Additional consolidation of the packing in the crystal is achieved through C-H⋯π and π-π stacking inter-actions. The inter-molecular inter-actions were qu-anti-fied and analysed using Hirshfeld surface analysis, revealing that H⋯H inter-actions contribute by far the most to the crystal packing (63.6%).

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...

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...
02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
