The title compound (1) was prepared by a previously reported method (Linsker & Evans, 1945). Crystals were grown as brown plates from boiling water. A crystal with approximate dimensions 0.15×0.50×0.55mm was mounted on a * To whom correspondence should be addressed. (20) = (2.5 + 0"70 tan0) °. Background intensities were measured for 5 s at both ends of a scan. Four standard reflections (002, 044, 040, 500) were remeasured after every 60 reflections; no significant loss of intensity was observed throughout data collection. 1610 independent reflections (Rant=0.015) were collected with 20 up to 50.5 ° [(sin0)/a= 0.600 A -~] and index range of h = -11 to 12, k = 0 to 10, l---12 to 0. Corrections for Lorentz and polarization effects were applied to the intensity data; no absorption or extinction corrections were carried out.

Remote Functionalized Nonlinear Optical Chromophore: Optimal Assembly in Crystals for Second Harmonic Generation

“…The basic crystallographic data are compiled in Table , and the unit cell is shown in Figure b. Crystal structure of AENA has been reported earlier; it belongs to the P 2 1 / c space group. Comparison of the bond lengths in AENA−CSA with those of AENA clearly shows that the former is a salt; the primary amine group of AENA is protonated in AENA−CSA.…”

Second Harmonic Generation from a Homologous Series of Molecular Crystals: Impact of Supramolecular Interactions

“…Crystal structures of AENA 20 and its salt with (S)-10camphorsulfonic acid 10 have been reported previously. We have now synthesized the salts of AENA with counterions ranging from formate to butyrate and investigated their structure; the basic crystallographic data for the four salts are collected in Table 1.…”
