Abstract

AbstractL‐valine (C5H11NO2), an essential amino acid of monoclinic space group P21, Z = 4 and lattice parameters a = 9.688 (2) Å, b = 5.267 (1) Å, c = 11.980 (2) Å and β = 90.75 (1)° and of size: 6.0 mm across and 0.5 mm thick was crystallized in silica gel under suitable pH conditions by reduction of solubility method. Density measurement and single crystal X‐ray diffraction were used to characterize the grown crystals. Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and scanning electron microscopic (SEM) studies were made and crystal packing also discussed.
