✦ Synopsis
A new ligand containing selenium, Se (CH 2 -N-Btrzole) 2 (L se ) (Btrzole = benzotriazole) and its cobalt(II) complex, Co(L se ) 2 (SCN) 2 , have been synthesized and the molecular structures of the title compounds have been determined by X-ray techniques. The L se is a meso-configuration with a symmetric plane through the Se center, the intermolecular weak interactions of Se-Se, Se-N and π -π stacking between benzotriazole rings to extend the molecular structure to two-dimensional network configuration. In the Co(II) complex, the metal center is in a six-coordinated octahedral environment. Two Co(II) atoms are linked by two ligands to form a 20-membered macrocycle; the adjacent macrocycles are linked by coordinated bond of Co-N bentrozole to extend an infinite double strained chain. The SOD activity of the ligand and Co(II) complex have been studied by using the pyrogallol autoxidation method; thermal properties and luminescent properties of Co(II) complex have been tested, and the details of those properties have been discussed.
