Abstract:
The crystal structures of the supra-molecular systems formed by pereth-oxy prism[6]arene (PS6) with 1,6-di-chloro-hexane (HexCl2), C90H96O12·2C6H12Cl2, and 1,6-di-iodo-hexane (HexI2), C90H96O12·2C6H12I2, are reported. PS6 encapsulates these linear dihaloalkanes, creating 1:1 host-guest systems (PS6·HexCl2 and PS6·HexI2). The structural details and host-guest inter-molecular inter-actions within the crystal networks are presented and discussed. In both crystal structures, the prism[6]arene macrocycle adopts a distorted cuboid shape, with the guest positioned perpendicular to its main axis.

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,...
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.

02:30Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...
