摘要
Solid-state phase transitions of 4-methylanilinium perchlorate (4-CH 3 C 6 H 4 NH 3 ·ClO 4 , 1) and tetrafluoroborate (4-CH 3 C 6 H 4 - NH 3 ·BF 4 , 2) were investigated with variable-temperature X-ray single-crystal structure analysis and thermal studies. Both 1 and 2 undergo first-order phase transitions and exhibit distinct dielectric anomalies at 385 and 247 K, respectively.
