摘要：

[PrCl3(15-crown-5)] was synthesized by electrocrystallization using a 1 : 1 metal to crown molar ratio. The complex crystallizes in the centric P2(1)/c space group with a = 8.191(4) angstrom, b = 14.245(9) angstrom, c = 14.226(6) angstrom, beta = 104.69(6)-degrees, and D(calc) = 1.93 g/cm3 for Z = 4 (20-degrees-C). A final R value of 0.070 was obtained via least-squares refinement using 2356 independent observed [F(o) greater-than-or-equal-to 5sigma(F(o))] reflections. The Pr ion is eight-coordinate with three chloride ions and the five oxygens of the crown ether directly coordinated.
