In this work, we use the amino acid L-threonine as a binder and the Ni+2 ion as a transition metal to obtain the crystal of L-threonine complexed with Ni. To obtain these crystals, we used the Slow Evaporation growth method, where a solution containing L-threonine and NiCl2.6H2O in the molar proportion (2:1) plus NaOH, to leave the basic pH, is left at rest to promote the growth of the crystals. To determine the crystalline structure of this material,...
