Abstract: The crystal and molecular structure of m-aminophenyl boronic acid (m-APBA)hydrochloride was determined by single crystal X-ray diffraction.The crystal parameters are as follows:monoclinic,space group P21/c,a=5.193 (3)nm,b=15.802(14) nm, c=10. 307(8)nm, Z=4.Each chloride ion is connected with 4 m-APBAH+ions through three Cl…H…Nhydrogen bonds and a Cl…H…Ohydrogen bond.Its coordination number is 4.The arrangement of m-APBA·HCl molecules within the crystal cell is determined by hydrogen bonding.

Key words: m-Aminophenyl boronic acid, Crystal structure, Molecular structure
