Crystal structure of (S)-2-amino-2-methylsuccinic acid
The title compound, C5H9NO4, crystallized as a zwitterion. There is an intra-molecular N-H⋯O hydrogen bond involving the trans-succinic acid and the ammonium group, forming an S(6) ring motif. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming C(7) chains along the c-axis direction. The chains are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming sheets parallel to the bc pl...
متن کاملCrystal Structure and Nanoparticles of Dinuclear Silver(I) Complex [Ag2(PPh3)2(μ-S-4nb-tsc)2(η1-S-4nb-tsc)2](NO3)2
Nanoparticles of a new dinuclear silver(I) complex [Ag2(PPh3)2(μ-S-4nb-tsc)2(η1-S-4nb-tsc)2](NO3)2, where 4nb-tsc = 4-nitrobenzylidenethiosemicarbazone and PPh3 = triphenylphosphine, were prepared in an ultrasonic bath and characterized by FT-IR and SEM. The crystal structure of a suitable single crystal prepared by slow evaporation was determined by single crystal X-ray diffraction. The compou...

The copper(II) complex [Cu(pic)2]·2H2O was synthesized with 2-picolinic acid (Hpic) and copper acetate as reactants by room temperature solid-solid reaction. The composition and structure of the complex was characterized by elemental analyses, single crystal X-ray diffraction, X-ray powder diffraction, FT-IR spectroscopy and thermogravimetry-differential scanning calor...
متن کاملCrystal structure of 2-amino-4,6-dimethoxypyrimidinium thiophene-2-carboxylate
In the title salt, C6H10N3O2 (+)·C5H3O2S(-), the 2-amino-4,6-di-meth-oxy-pyrimidinium cation inter-acts with the carboxyl-ate group of the thio-phene-2-carboxyl-ate anion through a pair of N-H⋯O hydrogen bonds, forming an R 2 (2)(8) ring motif. These motifs are centrosymmetrically paired via N-H⋯O hydrogen bonds, forming a complementary DDAA array. The separate DDAA arrays are linked by π-π sta...
متن کاملCrystal structure of [2-({2-[(2-azanidylbenzylidene)amino]benzylidene}amino)-4-chlorophenolato]nickel(II)
The title complex, [Ni(C20H14ClN3O)], with an asymmetrically chloride-appended Schiff base ligand has been synthesized and structurally characterized at 100 K. In the compound, the central nickel(II) ion has a square-planar coordination geometry with N3O donors of the π-conjugated tetra-dentate Schiff base ligand. In the crystal, the complexes are connected into an inversion dimer via an Ni⋯Ni ...
