Synthesis and structural characterization of a novel palladium Pd(II) complex with the amino acid L-citrulline (Cit, C6H13N3O3) are presented in this paper. Elemental analysis indicates a 1:2 metal/ligand molar composition for the complex, with the molecular formula PdC12H24N6O6. The compound was also characterized by infrared (IR) spectroscopic measurements and the crystal structure has been solved by powder X-ray diffraction data with simulated annealing strategy in real space. The Pd(II) complex crystallizes in the triclinic system with space group P-1 and cell parameters a = 4.6493(4) Å, b = 5.222(4) Å, c = 18.040(2) Å, α = 77.41(6)°, β = 94.72(7),° and γ = 101.45(7)°. The crystal structure confirms the presence of Pd(II) ions in a nearly square planar environment and the molecular formula with deprotonated citrulline as proposed by analytical and spectroscopic data.

AbstractThe title compound, N-[(lS,4R)-2-oxo-pinanyl]-β-alanine methylester, is an important starting material for the electrochemical preparation of chiral amidoalkylation reagents in the synthesis of chiral β-substituted β-amino acid derivatives. The investigation of its crystal structure reveals an arrangement of the carbonyl group and the amine function, which is influenced by a hydrogen bonding interaction. This conformation makes the molecule especially appropriate for further synthetical modification

Condensation of bis (ethane-1,2-diamine) copper(II) perchlorate with formaldehyde and diethyl malonate in basic methanol generates the new amino acid ester complex (ethyl hydrogen bis [(2-aminoethyl ) aminomethyl ] malonate )copper(II) perchlorate, [Cu(1)] (ClO4)2. Base- catalysed ester hydrolysis and decarboxylation in methanol of[Cu(1)]2+ yields, with reesterification, (methyl 3-[(2-aminoethy )amino]-2-[(2-aminoethyl) aminomethyl ]propionate)copper(II) perchlorate, [Cu(2)](ClO4)2. This complex crystallizes in the monoclinic space group P21/c, a 12.763(6), b 9.176(2), c 16.32(2)Ǻ, β 112.49 (6)°, Z 4, R 0.054 for 2626 independent 'observed' reflections. The copper ion lies in a near plane of four nitrogens with perchlorates occupying axial sites.
