Abstract
The synthesis and crystal structure of a new Co(II) compound with 2-(5-{6-[5-(pyrazin-2-yl)-1H-1,2,4-triazol-3-yl]-pyridin-2-yl}-1H-1,2,4-triazol-3-yl)pyrazine (H2Ptptp) are reported. The new compound [Co2(Ptptp)Cl2(H2O)2] · H2O (I) has been determined by single-crystal X-ray diffraction (CIF file CCDC no. 1010785) and characterized by elemental analyses and infrared spectrum. The structure I consists of two independent Co2+ ions, one Ptptp2− anion, two Cl− anions, two coordinated H2O molecules and one lattice H2O molecule. The three-dimensional (3D) supramolecular architecture is formed through the hydrogen bonds among adjacent units. Moreover, magnetic susceptibility measurements indicate that the compound exhibits weak antiferromagnetic coupling interaction.
