New cobalt and iron pivalate complexes with 2,2′:6′,2″-terpyridine: synthesis, structure, and magnetic properties

The mononuclear complexes (η 3 -terpy)M(Piv) 2 ·MeCN (M = Fe ii ( 3 ) and Co ii ( 4 ), and Piv is the pivalate anion) were synthesized by the reactions of polymeric iron( ii ) and cobalt( ii ) pivalates with 2,2′:6′,2″-terpyridine (terpy). The oxidation of compound 3 affords the pentanuclear heteros...

Description
Summary:The mononuclear complexes (η 3 -terpy)M(Piv) 2 ·MeCN (M = Fe ii ( 3 ) and Co ii ( 4 ), and Piv is the pivalate anion) were synthesized by the reactions of polymeric iron( ii ) and cobalt( ii ) pivalates with 2,2′:6′,2″-terpyridine (terpy). The oxidation of compound 3 affords the pentanuclear heterospin iron( ii,iii ) complex (η 3 -terpy)Fe 5 (μ 4 -O)(μ 3 -OH)(μ-OH) 2 (μ-Piv) 7 (η 1 -Piv) 2 ( 5 ). All compounds were characterized by X-ray diffraction.
