The synthesis, crystal structure and spectroscopic studies are reported for the salt m-anisidinium nitrate. A single-crystal  X-ray investigation has shown that this compound crystallizes in the non-centrosymmetric space group Cc with the lattice parameters: a = 5.744(3) Å, b = 14.968(6) Å, c = 10.178(4) Å; b  = 96.910(7)o; V = 868.6(6)Å3 ; Z = 4. The structure was solved from 1973 independent reflections with R1 = 0.033 and wR2 = 0.088. The hydrogen atoms of the protonated amine undergo hydrogen bonding interactions with oxygen atoms of three different nitrate anions forming 2-dimensional sheets. Solution NMR results are consistent with the X-ray structure. A measured optical band gap of 3.35eV indicates m-anisidinium nitrate is a wide-band-gap dielectric material.

The structure of bis(3-Phenylpropylammonium) dichromate(VI) was determined from X-ray diffraction data. The compound crystallizes in the monoclinic system (space group P21/c) with the lattice parameters: a = 7.9379(2) Å, b = 36.2439(16) Å, c = 7.5753(3) Å; B = 96.069(2); V= 2167.20(14) Å3 and Z = 4. The structure was solved from 4959 independent reflections with R = 0.043 and Rw = 0.105. The structure consists of discrete dichromate anions (Cr2O72-) with eclipsed conformation stacked in layers parallel to (a, c) plane at y = 0 and ½. These anions are linked via the 3-phenylpropylammonium cations by N—H…O and C—H…O hydrogen bonds, forming a two-dimensional supramolecular network. Crystal structure and spectroscopic studies are reported for the bis(3-phenylpropylammonium) dichromate(VI).
