The reaction of praseodymium trifluoroacetate with 15-crown-5 ether in acetonitrile-methanol (3:1) gave a complex fromulated as 2(C10H20O5).This compound was recrystallised and the X-ray crystal structure determined by the heavy-atom method and refined by least-squares methods to a final R value of 0.075.The recrystallised complex turned out to have a different formula, as indicated in the title.It crystallises in the monoclinic space group P21/m, with lattice parameters a=9.124(1), b=31.607(4), c=13.006(2) Angstroem, beta=99.55(1) deg, and Z=2.These are two praseodymium sites.One metal ion is nine-co-ordinate and is bonded to the macrocycle , three bridging trifluoroacetate groups , and a bridging hydroxide ion which lies in the mirror plane y=1/4.This gives rise to dimeric cations 2+, the co-ordination polyhedron of which may be regarded as arising from distortion of a square antiprism by addition of a ninth ligand.The second praesodymium is eight-co-ordinate with a fairly regular square-antiprismatic co-ordination polyhedron consisting of one bidentate trifluoroacetate and three bridging bidentate trifluoroacetates that give rise to infinite polymeric zigzag chains parallel to a.
