%X Molecular salts, specifically 1-phenylethan-1-aminium 4-hydroxy-3-methoxybenzoate (1), 1-phenylethan-1-aminium 4-hydroxy-3,5-dimethoxybenzoate (2), and 1-phenylethan-1-aminium 3-(4-hydroxy-3-methoxyphenyl)prop-2-enoate (3), were successfully synthesized. The structures of [C<sub>8</sub>NH<sub>12</sub>]<sup> </sup>[C<sub>8</sub>H<sub>7</sub>O<sub>4</sub>]<span style="font-size:10px;"><sup>-</sup></span>(1), [C<sub>8</sub>NH<sub>12</sub>]<sup> </sup>[C<sub>9</sub>H<sub>9</sub>O<sub>5</sub>]<sup>-</sup>(2), and [C<sub>8</sub>NH<sub>12</sub>]<sup> </sup>[C<sub>10</sub>H<sub>9</sub>O<sub>4</sub>]<sup>-</sup>(3) were confirmed through single crystal X-ray diffraction, revealing that they belong to the tetragonal and monoclinic crystal systems. This synthesis methodology underscores the effectiveness of salt formation as a strategy in crystal engineering to modulate physicochemical properties, which may enhance separation efficiency and broaden applicability in pharmaceutical or industrial contexts.
