Abstract

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 calorimetry. The CRYSTAL STRUCTURE of the copper (II) complex belongs to triclinic system and space group, with cell parameters of a=5.1274 (16) Å, b=7.641 (2) Å, c=9.209 (2) Å, a=74.91 (2) o, b=84.56 (2) o, g=71.58 (3) o, V=338.48 (15) Å 3, Z=1, F (000) =175, R1=0.0530, and wR2=0.1141. The Cu (II) ion is six-coordinated through two nitrogen atoms from two pyridine rings and four carboxyl oxygen atoms from four different 2-PICOLINIC ACID anions, forming an elongated octahedral geometry. The interaction of carboxylate O and Cu (II) forms an one-dimensional chain structure, and the complex exhibits a two-dimensional layered structure by hydrogen bonds. The THERMAL DECOMPOSITION processes of the complex under air include dehydration and pyrolysis of the ligand, and the final residue at about 400 o C is copper oxide.
