Abstract
[PrAl (CF3COO)(2) (CF3CHOO) (C2H5)(2) (C4H8O)(2)](2) M-r = 1420. 56, monocl inic, P2(1)/n, a = 10. 651 (6) , b = 24. 276(9), c = 11. 110(5) Angstrom, b eta = 107. 650 (4)degrees , V = 2737. 4(1) Angstrom (3) , Z = 2, D-c = 3. 4 5 g/cm(3) , F(000) = 2816 , T = 233K, MoK alpha radiation (lambda= 0. 71069 Angstrom), mu(MoK alpha) = 38. 017 cm(-1) , R = 0. 048 for 2847 observed r eflections (I greater than or equal to 3 sigma(I)). It is isostructural wit h [LnAl (CF3COO)(2) (CF3CHOO) -R-2 (C4H8O)(2)](2) (Ln = Ho, R = Et; Ln = Nd t Y, R = Bu-1). Pr3+ is coordinated by eight oxygen atoms from five bridgin g ligands and two THF forming a distorted bicap-prism.
