Reaction of Co(II) perchlorate hexahydrate and anhydrous Co(II) chloride with the ligand 2-(2'-pyridyl)quinoxaline (L) leads to the formation of the novel five- and six-coordinated complexes CoLCl2(DMF) (1) and [CoL2(H2O)(2)](ClO4)(2). H2O 2CH(3)OH (2), correspondingly. The crystal structures of the above complexes show a trigonal bipyramidal geometry around the metal atom for complex 1 and a distorted octahedral geometry for complex 2.
