title: Dimethano-lbis[4,4,5,5-tetra-methyl-2-(5-methyl-imidazol-4-yl)-2-imidazoline-1-oxyl-3-oxide-κO,N]cobalt(II) diperchlorate.
abstract: In the mononuclear title complex, [Co(C(11)H(17)N(4)O(2))(2)(CH(3)OH)(2)](ClO(4))(2), the cobalt(II) atom lies on a symmetry centre and is coordinated by two O,N-bidentate ligands and two trans-arranged O atoms of the methanol mol-ecules in a slightly distorted octa-hedral geometry. In the crystal structure, cations and anions are linked by N-H⋯O and O-H⋯O hydrogen bonds into layers parallel to the bc plane.
