The interaction of PrCl3 with 1,3-bis(1,3-dimethyl-1H-pyrazol-4-yl)-1,3-propanedione in aqueous ethanol in the presence of a base and 1,10-phenanthroline was studied. It was shown that the composition of the products was dependent on the reaction conditions. The solvate [Pr(L)3(Phen)]•3PriOH crystallizes in a monoclinic crystal system (P21/c space group, a = 12.2239(12) Å, b = 20.3403(19) Å, c = 26.134(3) Å, β = 102.380(2)° at 150 K). Absorption spectra of the complex in solution, as well as the spectra and the kinetic parameters of photo-luminescence were investigated.
在碱和 1,10-菲罗啉的存在下,研究了在乙醇水溶液中 PrCl3 与 1,3-双(1,3-二甲基-1H-吡唑-4-基)-1,3-丙二酮的相互作用。结果表明,产物的组成取决于反应条件。溶质 [Pr(L)3(Phen)]-3PriOH 在单斜晶系中结晶(P21/c 空间群,a = 12.2239(12) Å,b = 20.3403(19) Å,c = 26.134(3) Å,β = 102.380(2) °,150 K 时)。研究了该复合物在溶液中的吸收光谱以及光致发光的光谱和动力学参数。
