Crystal structure of 2-[(naphthalen-2-yl)meth-yl]iso-thio-uronium bromide
1Institute of Physics AS CR, v.v.i., Na Slovance 2, 182 21 Prague 8, Czech Republic.
Abstract:
Herein we report the crystal structure of 2-[(naphthalen-2-yl)meth-yl]iso-thio-uronium bromide, C12H13N2S+·Br-, which crystallizes in the monoclinic P21/c centrosymmetric space group. The asymmetric unit contains one 2-[(naphthalen-2-yl)meth-yl]iso-thio-uronium cation and one bromide anion. The methyl-ene carbon lies in plane of the naphthalene core. In comparison with reference structures, elongation of C-S bonds as well as tilting of the iso-thio-uronium group is observed. Given the ionic nature of the compound, the structure is held by charge-assisted N-H⋯Br hydrogen bonds, with a noteworthy contribution of dipole-dipole inter-actions, which form bilayers in the structure. The bilayers are held by the weak London forces.

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...
02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

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...

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,...
