Abstract: | Summary The structure of the hexaazamacrobicycle, sarcophagine, (diAMMEsar)·2H2O, formed by extracting Co ion from the [Co(diAMMEsar H2)]Cl5·-H2O cage with 8-hydroxyquinoline, has been determined by elemental analysis, and i.r., u.v.-vis., 1H-n.m.r. and mass spectroscopies. Two octahedral complexes, [M(diAMM-EsarH2)]Cl4·2H2O (M = NiII or CuII), have been prepared and characterized. The e.s.r. spectrum of the CuII complex in the solid state indicates spin-exchange interaction between the CuII ions. However, in CD3OD-D2O (10%) at 77K, the spectrum is characteristic of a compound having axial symmetry (d x 2−y 2). |
