Macrobicyclic antimony-capped

Complexes with type I.II ligands are usually referred to as boron (tin, germanium, silicon, antimony)-capped macrobicyclic dioximates (oximehydrazonates, azineoximates). Their abbreviated... 

The spectral characteristics for tin-, germanium-, and antimony-capped macrobicyclic iron(II) dioximates differ greatly from those of the corresponding boron-capped complexes discussed above. 

The electrochemical behaviour of the macrobicyclic boron-, germanium-, antimony-, and tin-capped iron, cobalt, and ruthenium dioximates has been studied by cyclic voltammetry, polarography, and electrolytic experiments [41, 52, 64, 65, 68, 73, 74, 77, 78, 328-330]. For every metal ion, the dependence of the redox potentials on the electronic characteristics of the substituents in the dioximate... 

Cyclic voltammetric data (mV) for macrobicyclic boron-, tin-, antimony- and germanium-capped iron(II) oximehydrazonates and a-dioximates [73, 74, 188],... 

The redox properties of macrobicyclic iron(II) mono- and binuclear oximehydrazonates and a-dioximates formed by capping with antimony(V) and germanium(IV) triorganyles were studied by cyclic voltammetry [73, 74]. The electrochemical behaviour of these compounds is similar to that of analogous boron- and tin-capped clathrochelates. Oxidation of all mononuclear complexes involves a one-electron process, assigned to the oxidation of encapsulated iron(II) ion to iron(III) ion. This process is electrochemically...
