With nitric acid; In methanesulfonic acid; at 20℃; for 6.0h; | The title compound was synthesized by mixing equimolar portions of N,N'-Diphenylguanidine and nitric acid using methanol as solvent. At first the starting material, nitric acid was dissolved in methanol and then further N,N'-Diphenylguanidine was added tothis solution, by continuous stirring, until complete neutralization occurred resulting in a pale brown colored solution. The solution was made to stir for 6 h using a magnetic stirrer in order to achieve homogeneity at room temperature and the resulting solution was filtered in a 500 mL clean borosil beaker through Whatmann filter paper. The beaker was covered with aluminum foil in order to control the rate of evaporation. The purity of the synthesized salt was further improved by successive recrystallization. The reaction scheme is given in Fig. 1. A well defined pale brown colored transparent single crystal of DPGN was harvested after a period of 46 days and the photograph of the as grown DPGN crystal is shown in Fig. 2. |

at 20℃; for 6.0h; | Equimolar methanolic solutions of picric acid (Analytical grade-Sigma Aldrich) and N,N'-<strong>[102-06-7]diphenylguanidine</strong> (Analytical grade-TCI chemicals) were mixed and the resulting solution was stirred well at room temperature for 6 h. A yellow colour precipitate was obtained after evaporation of the solvent. The precipitate was repeatedly recrystallized in acetone. Transparent and yellow coloured single crystals of N,N?-diphenylguanidinium picrate: diacetone solvate (DPGPD) were harvested after 20 days by slow evaporation-solution growth technique |

The resultant solution was filtered in order to remove the impurities and a clear homogenous solution left undisturbed in a covered vessel for slow evaporation technique at ambient temperature. After 30 days,bright transparent crystals of DPGPTS were harvested and the photographic image is provided in Fig. S1. The reaction scheme is shown below. |
