Abstract:
A new pseudopolymorph of berberine, 9,10-dimeth-oxy-5,6-di-hydro-2H-7λ5-[1,3]dioxolo[4,5-g]iso-quinolino-[3,2-a]isoquinolin-7-ylium chloride methanol monosolvate, C20H18NO4 +·Cl-·CH3OH, was obtained during co-crystallization of berberine chloride with malonic acid from methanol. The berberine cations form dimers, which are further packed in stacks. The title structure was compared with other reported solvates of berberine chloride: its dihydrate, tetra-hydrate, and ethanol solvate hemihydrate. Hirshfeld analysis was performed to show the inter-molecular inter-actions in the crystal structure of the title compound, and its fingerprint plots were compared with those of the already studied solvates.

Ionic Crystal Structures
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...

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,...
