The hybrid density functional theory B3LYP method with the 6-31G(d) basis set and the Gaussian 98 program has been used for calculating the geometric parameters of the Mn(II), Co(II), Ni(II), and Cu(II) complexes with NNSS-donor macrocyclic ligands forming in the course of template processes in the M(II)-dithiooxamide-formaldehyde systems. The bond lengths and bond angles in the complexes with the MN2S2 metal chelate core are reported. For all M(II) ions, the extra six-membered chelate ring that form as a result of template assembly is rotated through a rather large angle with respect to two five-membered rings and the ring itself is not planar.
