| Abstract: | Doubly-armed diazatetralactams constitute a new series of easily synthesized tetralactams. The structural study of the calcium complexes of their N,N′-dimethyl acetamido and (2-pyridylmethyl) derivatives was performed by IR, 1H, 13C NMR spectroscopies and molecular modeling. These complexes showed a C2 symmetry and a high number (8–9) of coordination around the calcium atom. |
