Magnetic properties, porphyrazines

Magnetic Properties. The magnetic susceptibilities of the ferrous and ferric porphyrazines 11,13, and 16a-d are reported in Table IV. For 11, which is a square-planar d6 system, the effective moment of 3.82 is consistent with a... 

B = molybdocene(IV) dithiol (70b). The solitaire porphyrazines exhibited rich redox chemistry, and could be oxidized with ferrocenium hexafluorophosphate to yield the paramagnetic Mo(V) species H2[pz(A3B)], A = di -ferf-butyl phenyl, B = molybdocene(V) dithiol (72a) and H2[pz(A3B)], A = dipropyl, B = molybdocene(V) dithiol (72b), which were studied by EPR (Scheme 13). Additionally, 70a was centrally metalated with Cu(II), to form Cun[pz(A3B)], A = di-ferf-butyl phenyl, B = molybdocene(IV) dithiol (71), which was then oxidized to Cun[pz(A3B)], A = di-terf-butyl phenyl, B = molybdocene(V) dithiol (73) and its magnetic properties investigated. 

In particular, Fitzgerald s new route for the preparation of alkyl substituted dinitriles was used to prepare ethyl appended porphyrazines that were centrally metalated with iron and rhodium (Schemes 4 and 5). The main focus of Fitzgerald s work was on the magnetic and electronic properties of the metalated octaethylpor-... 

In the present work, our aim has been prepared to different peripheral porphyra-zines which include eight 3-methylbutan and 3-phenylpropyl groups. Peripherally-functionalized porphyrazines have the potential to exhibit novel optical, magnetic and electronic properties [3],...
