Abstract
A series of new heterospin complexes based on metal
hexafluoroacetylacetonates with spin-labeled benzonitriles (NIT-
p-PhCN and
NIT-
m-PhCN) were synthesized. It was shown that Ìn(hfac)
2 and
Co(hfac)
2 complexes with NIT-
p-PhCN are heterospin layered polymers
magnetically ordered below 9-11 K. Among Ì(hfac)
2 complexes with
NIT-
m-PhCN possessing molecular or chain structures there are no magnetic
ordering solids.
Key words. Nitronyl nitroxides - metal complexes - structure-
molecular magnets.
