Abstract:
We have addressed several interesting issues related to trinitromethane: the propellerlike arrangement of its nitro groups, its lower-than-predicted (although still high) acidity, its aci tautomerization, and the absence of expected very short C-HO intermolecular bridges in the crystal. A combination of crystallographic and computed data was used in our analysis. The structural features mentioned and the anomalous acidity can be attributed to intra- and/or intermolecular electrostatic interactions. Decomposition via C-NO(2) bond scission may occur before aci tautomerization can take place.

Crystal 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,...
