TL;DR: In this paper, the X-ray diffraction data showed that DyI2Et(DME)2 and DyIEt2DME2 were synthesized by the reaction of DyI 2 with ZnEt2 in dimethoxyethane.
Abstract: The ethyl complexes of dysprosium DyI2Et(DME)2 and DyIEt2(DME)2 were synthesized by the reaction of DyI2 with ZnEt2 in dimethoxyethane. The complexes were isolated as pale yellow crystals. According to the X-ray diffraction data, these compounds contain, in addition to DyI2Et(DME)2 and DyIEt2(DME)2, triiodide DyI3(DME)2 (1). The reactions of CdMe2 with NdI2, DyI2, and TmI2 proceed in a similar way and afford methyl iodide complexes of lanthanides. The reaction of GaEt3 with DyI2 gave the ionic complex of trivalent dysprosium [GaEt4]−[DyI2(THF)5]+ (2).

TL;DR: In this article, the purity and composition of the prepared compounds have been elucidated from X-ray diffraction analysis, IR spectroscopy, elemental analysis, and thermogravimetry studies; thermal decomposition of the non-valence compounds has been studied.
Abstract: Nanostructured non-valence compounds based on coordination compounds of zinc(II) with phthalic and terephthalic acids have been prepared. The purity and composition of prepared compounds have been elucidated from X-ray diffraction analysis, IR spectroscopy, elemental analysis, and thermogravimetry studies; thermal decomposition of the non-valence compounds has been studied as well. The prepared self-assembled compounds are co-precipitated with one water molecule and 1.5 acetic acid molecules per unit of the dicarboxylic acid: [Zn4(OH)6·o-C6H4(COO)2]·H2O·1.5CH3COOH and [Zn4(OH)6·p-C6H4(COO)2]·H2O· 1.5CH3COOH.

TL;DR: In this paper, a preparation method of a zinc gluconate-lysine eutectic crystal, which comprises the following steps: adding amorphous compounds of zinc gluclate and lysine into a zincgluclate supersaturated water solution for suspension, adding a counter solvent for sedimentation, and filtering to obtain the ZGLU-Lysine EUTECTIC crystal, has been described.
Abstract: The invention discloses a preparation method of a zinc gluconate-lysine eutectic crystal, which comprises the following steps: adding amorphous compounds of zinc gluconate and lysine into a zinc gluconate and lysine supersaturated water solution for suspension, adding a counter solvent for sedimentation, and filtering to obtain the zinc gluconate-lysine eutectic crystal. Under the Cu-Kalpha radiation, the zinc gluconate-lysine eutectic crystal has characteristic diffraction peaks when the interplanar distance of the X-ray powder diffraction represented by the angle 2theta is 13.45, 13.84, 15.37, 16.78, 20.40, 21.86, 22.64, 24.15, 24.76, 25.05, 25.37, 26.84, 27.22, 27.68, 30.03, 31.10, 31.60, 33.33, 34.44, 35.94, 36.32, 36.68, 37.08, 37.32 or 38.53. The preparation method is simple to operate and easy to control, and has the advantages of single reaction condition and favorable reproducibility; and the prepared zinc gluconate-lysine eutectic crystal has the advantages of high purity and low impurity content.
