| Popis: | A new R2edda-type ester, diisobutyl (S,S)-2,2'-(1,2-ethane-diyldiimino) di(4-methylpentanoate) dihydrochloride, [(S,S)-H2iBu2eddl]Cl2, 1, and its palladium(II) complex, dichloro(diisobutyl (S,S)-2,2'-(1,2-ethanediyldiimino) di(4-methylpentanoate))palladium(II), [PdCl2{(S,S)-iBu2eddl}], 2, were synthesized and characterized by elemental analysis, as well as IR and NMR spectroscopy. It was found that complex 2 was obtained as mixture of two diastereoisomers, observed in NMR spectra. The crystal structure of compound 1 was determined by X-ray diffraction studies and is described. The isolated crystals consisted of one dicationic species [(S,S)-H2iBu2eddl]2+ and two Cl-. The crystal system was tetragonal with the space group P42. Hydrogen bonds significant for the manner of packing are N-H1N···Cl, 3.049(3) Å, 159(3)° and N-H2N···Cl, 3.100(3) Å, 164(3)°. An infinite chain was formed building a one layer structure, usual for these types of compounds. The C2 symmetry axis of the compound passes through the C1-C1i bond vector and lies perpendicular to the plane N2Cl2. |
