Their composition has been studied using inductively coupled plasma atomic emission spectroscopy (ICP-AES), CHNS-analysis, IR spectroscopy, powder X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The obtained nanoparticles were tested on chickens, and the best average daily increase in their weight was observed when feeding them with ferrous cysteinate nanoparticles in comparison with ferrous sulfate at a 10 times higher dosage.

The crystal structure of new isostructural complex Y(thd) 3 ( I ), Ho(thd) 3 ( II ), Tm(thd) 3 ( ... more The crystal structure of new isostructural complex Y(thd) 3 ( I ), Ho(thd) 3 ( II ), Tm(thd) 3 ( III ) and Lu(thd) 3 ( IV ) are determined: space group Pna 2 1 , Z = 8 ( a = 41.956(8) A, b = 17.837(4) A, с = 9.742(2) A, V = 7291(3) A 3 for I ; a = 41.778(2) A, b = 17.8045(6) A, с = 9.6862(3) A, V = 7204.9(4) A 3 for II ; a = 41.884(5) A, b = 17.758(2) A, с = 9.672(1) A, V = 7193.7(2) A 3 for III, a = 41.942(8) A, b = 17.712(4) A, с = 9.711(2) A, V = 7214(2) A 3 for IV ). The crystal structures of I – IV are molecular and consist of discrete monomeric Ln(thd) 3 molecules (Ln = Y, Ho, Tm, Lu). The highest quantum yields of luminescence are obtained for Tb(dpm) 3 (77%), [Tb(thd) 3 ] 2 (25%) and Dy(thd) 3 (5%), [Dy(thd) 3 ] 2 (0.4%). Thermogravimetric investigations show that the volatility of complexes increases from Yb(thd) 3 to Pr(thd) 3 . Melting points of the complexes are close to the known literature data. The complex compounds we synthesized were characterized by NMR in a CDCl 3 solution. Quantum chemical calculations are shown that for the Y(III) complexes with thd-ligands the phase of dimeric molecules is energetically more stable.
