No full textCrystals of the title compound, C11H18N2O2·HBr, are monoclinic, space group P21, with a=7.339(3), b=13.246(7), c=7.340(4) Å, β=116.94(5)°, and Z=2. The structure was solved by direct methods and refined by full matrix least-squares calculations to an R value of 0.046 for 1218 observed reflections. The piperidine ring, in a chair conformation, is perpendicular (90.6°) to the strictly planar pyrrolidine-2,5-dione ring. Br− is hydrogen bonded to the positively charged piperidine N1 atom. Bond lengths and valence angles are comparable to those of various related compounds

The Crystal Structure of Tetraethilenglycoltrinitrato Lanthanum(III): An Example of Undecacoordination.
No full textThe 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
