همنهشت، ساختار بلوری و آنالیز سطح هیرشفلد نمک اسیدی [4-متیل فنیل آمونیوم] [(O-فنیل)(هیدروکسیل)فسفات]، [4-CH3-C6H4NH3][(C6H5O)P(O)(O)(OH)]

The synthesis and X-ray diffraction analysis of a new acidic salt, [4-methyl-phenyl ammonium][(O-phenyl)(hydroxyl)phosphate], [4-CH3-C6H4NH3][(C6H5O)P(O)(O)(OH)], is reported. This compound crystallizes in the monoclinic system, with space group P21/c (a = 9.5147(4) Å, b = 23.2158(10) Å, c = 13.2740(6) Å and b = 111.244(4)°) with four independent components including two cations and two anions in the asymmetric unit. In the crystal, adjacent components are linked together through N–H∙∙∙O and O–H∙∙∙O hydrogen bonds building a ladder arrangement along [100] axis. The Hirshfeld surface analysis and two-dimensional fingerprint plot were used to study intermolecular interactions in the structure. The N–H∙∙∙O and O–H∙∙∙O hydrogen bonds are the characteristic interactions (red areas in the Hirshfeld surfaces). Two sharp spikes in the fingerprint plots of two anions are related to the O…H(O) contacts, while one nearly sharp spike in the fingerprint of two cations is assigned to the O...H(N) contacts.
