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.
