Reseña del libro "Synthesis and Structural Determination Byx-Ray Diffraction"
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, X-Ray Diffraction measurements were performed. Data treatment and structure resolution were performed using Bruker's SHELXTL package and using the Direct Methods structural determination mechanism, which is one of the most widely used alternatives to circumvent the problem of phases in the structural determination of small molecules. With these analyses, it was determined that L-threonine complexed with Ni has a chemical formula Ni(II)(L-threonine)2(H2O)2 and crystallizes in orthorambic symmetry with spatial group The knowledge of the structure of this material, opens possibilities of studies that can be performed on it.
