Abstract:
The cocrystal formed between 2,3-di-amino-pyrazine and 2,3,5,6-tetra-fluoro-phthalic acid, crystallizes as the solvated salt bis-(2,3-di-amino-pyrazin-1-ium) 2,3,5,6-tetra-fluoro-phthalate-2,3,5,6-tetra-fluoro-phthalic acid (1/1), 2C4H7N4 +·C8F4O4 2-·C8H2F4O4, in the triclinic space group P1 with one unique protonated 2,3-di-amino-pyrazinium cation, one half a tetra-fluoro-phthalic acid mol-ecule and one half of a tetra-fluoro-phthalate anion. The cocrystal forms a supra-molecular network with cooperative neutral and charge-assisted hydrogen bonding. In this, the linear network of alternating pyrazinium and tetra-fluoro-phenyl moieties is crosslinked through bifurcated hydrogen bonds of two amino H atoms and a carboxyl oxygen to form a corrugated two-dimensional network.

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.

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...
