Abstract
The title compd. is monoclinic, space group P21/n, with a 12.75(1), b 16.84(1), c 8.15(1) Å, and β 101.27(3)°; = 2.01 for Z = 4. Final R = 0.049 for 2310 reflections. At. parameters are given. The pentadentate org. ligand, wraps around the metal ion which is also bound to 3 chelate nitrato groups, thus achieving the rather uncommon coordination. Five La-O(nitrate) (mean 2.61 Å) compare well with the two La-O (alc.) bond distances (mean 2.58 Å). One La-O (nitrate) (2.79 Å) and the three La-O(ether) bond distances (mean 2.70 Å) are significantly longer. Weak intra- and intermol. H bonds are also present.File in questo prodotto:
