The e.s.r. study of a single crystal of NN′-ethylenebis(acetylacetoneiminato) cobalt(II)-doped NN′-ethylenebis-(acetylacetoneiminato) nickel(II), [Co(acacen)] and [Ni(acacen)], is reported; determination of the ground state of the cobalt complex was attempted. [Ni(acacen)] Is isomorphous with [Co(acacen)] as shown by a single-crystal structural determination: the doped crystals are orthorhombic, space group Pna21, Z = 4, a = 12.18(1), b = 10.28(1), and c = 10.37(1). The equatorial principal axes of the g tensor were found to be almost parallel with the cobalt-ligand bond, rather that between these bonds, as expected.

Abstract
The e.s.r. study of a single crystal of NN′-ethylenebis(acetylacetoneiminato) cobalt(II)-doped NN′-ethylenebis-(acetylacetoneiminato) nickel(II), [Co(acacen)] and [Ni(acacen)], is reported; determination of the ground state of the cobalt complex was attempted. [Ni(acacen)] Is isomorphous with [Co(acacen)] as shown by a single-crystal structural determination: the doped crystals are orthorhombic, space group Pna21, Z = 4, a = 12.18(1), b = 10.28(1), and c = 10.37(1). The equatorial principal axes of the g tensor were found to be almost parallel with the cobalt-ligand bond, rather that between these bonds, as expected.
