The generation of a trinuclear cobalt (II) core supported by differing tridentate acetate bridges

Formation of a quasi-symmetrical mu 3-carbonato-bridged self-assembled heteromolecular triangle of Ni(II), [(mu 3-CO 3){Ni 2(salmeNH) 2(NCS) 2}{Ni(salmeNH 2) 2].Et 2O.H 2O (HsalmeNH = 2-[(3-methylamino-propylimino)-methyl]-phenol) involves atmospheric CO 2 uptake in a neutral medium, by spontaneous self-reorganization of the starting mononuclear Ni(II)-Schiff-base complex, [Ni(salmeNH) 2]. The environment around Ni(II) in two of the subunits is different from the third one. The starting complex, [Ni(salmeNH) 2], and one of the possible intermediate species, [Ni(salmeNH 2) 2(NCS) 2], which has a very similar coordination environment to that in the third Ni(II) center, have been characterized structurally. A plausible mechanism for the formation of such a triangle has also been proposed. The compound shows a very strong antiferromagnetic coupling. Fit as a regular triangular arrangement gave J = -53.1, g = 2.24, and R = 1.5 x 10 (-4).
