Solid–Solid Synthesis, Crystal Structure and Thermal Decomposition of Copper(II) Complex of 2-Picolinic Acid
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 (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 of 3-acetoxy-2-methylbenzoic acid
In the title mol-ecule, C10H10O4, the carb-oxy-lic acid group is twisted by 11.37 (15)° from the plane of the benzene ring and the acet-oxy group is twisted from this plane by 86.60 (17)°. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming inversion dimers with the expected R 2 (2)(8) graph-set motif.
متن کاملCrystal structure of 4-benzamido-2-hydroxybenzoic acid
In the title compound, C14H11NO4, the dihedral angle between the mean planes of the aromatic rings is 3.96 (12)° and an intra-molecular O-H⋯O hydrogen bond closes an S(6) ring. A short intra-molecular C-H⋯O contact is also seen. In the crystal, carb-oxy-lic acid inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(8) loops. Conversely, the N-H group does not form a hydrogen...
