✦ Synopsis

Three new cobalt(II) complexes [Co(bbta) 2 (MeOH) 2 (NCS) 2 ] (1), [Co(bbta)(DMF) 2 (NCS) 2 ] n (2) and [Co(bbta) 3 (NCS) 2 ] n (3) were synthesized in the different solvent systems using the flexible ligand 1,2-bis(benzotriazol-1-yl)ethane (bbta) and the anion ligand thiocyanate. The X-ray diffraction analysis shows that 1 is a mononuclear, while 2 and 3 form the different zigzag chain structures. A conformation analysis of the ligand molecule demonstrates that the diversity in the ligand conformations leads to a variation in structural motifs.
