Abstract:
The title salt, C14H16N+·C6H7AsNO3 -·H2O or [(C6H5CH2)2NH2][H2NC6H4As(OH)O2]·H2O, (I), was synthesized by mixing an aqueous solution of (4-amino-phenyl)-arsonic acid with an ethano-lic solution of di-benzyl-amine at room temperature. Compound I crystallizes in the monoclinic P21/c space group. The three components forming I are linked via N-H⋯O and O-H⋯O inter-molecular hydrogen bonds, resulting in the propagation of an infinite zigzag chain. Additional weak inter-actions between neighbouring chains, such as π-π and N-H⋯O contacts, involving phenyl rings, -NH2 and -As(OH)O3 functions, and H2O, respectively, lead to a three-dimensional network.

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...

01:28Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the...
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,...
