| Abstract: The ternary coordination compounds of lanthanideions with β-diketone and diantipyrylmethane (DAM) have been studied.Spectrophotometric methods were employed in the study of the ternary coordination compounds of lanthanide ions.Nd3+,Ho3+ and Er3+,with 1-phenyl-3-methyl-4-dichloroacetyl-pyraoone-5(HPMDCP) and DAM in water-ethanolic solvent systems.Shift and increase in the absorption maxima for the hypersensitive transitions were observedfor the water-ethanolic solutions of Ln3+(Ln=Nd,Ho,Er) chlorides and their binary and ternary coordinationcompounds with HPMDCP and DAM.For the ternary coordination compouds in solution,the component ratio of Ln3+ :HPMDCP:DAM=1:3:1 was determined using the methods of continuous variation and equilibrium-shift.The corresponding coordination compound of neodymium was prepared and characterized in solid state.Elemental analyses of NdC59H51N10O8Cl6 are calculated:C,51.16;H,3.71;N,10,12,found:C,50.32;H,3.68;N,9.14.Infrared spectrum shows disappearance of the 2400-2800cm-1 hydroxylic absorption for HPMDCP upon coordination and shift of the carbonyl absorption maximum toward lower frequency to 1630cm-1 Thermogravimetric and differential thermal analyses show decomposition of Nd(PMDCP)3.DAM which starts at 236℃ and completes at 516℃.The oscillator strengths(P)for the hypersensitive transitions were calculated for these Ln3+ coordination compounds from the area under the corresponding absorption bands.The linear relation between the P values of Nd3+(Er3+)and those of Ho3+ was studied.By means of the relation of the increase in the oscillator strength with the coordination ratio ,the component ratio for Ln(PMDCP)3·DAM was also reconfirmed. |
