Original Paper


The structures of the oligomers of Co(II), Ni(II), Cu(II) and Zn(II) β-diketonates and their stability with respect to dissociation into the monomeric components were studied with the use of density functional theory [DFT B3LYP/6-311++G(d,p)] method taking additionally into account corrections for dispersion interactions in CAM and D3BJ approximations. The calculated geometries of the oligomers well match those experimentally determined, but stabilization energies obtained at the B3LYP-CAM and B3LYP-D3BJ approximations are significantly overestimated.
