Heptanuclear high-spin complex compounds based on S-donors

subject

description

Abstract The precursors [Fe(III)( SY L)Cl] ( SY LH 2 ) =  N , N ′-bis(1-hydroxy-Y-2-benzyliden)-1,6-diamino-3-thiohexane, (Y = H, 3EtO, 5Me) are high-spin ( S  = 5/2) complexes. The precursors are combined with [Fe(II)(CN) 6 ] 4− and [Co(III)(CN) 6 ] 3− to yield star-shaped heptanuclear clusters, [Fe(II)(CN–Fe(III) SY L) 6 ]Cl 2 and [Co(III)(CN–Fe(III) SY L) 6 ]Cl 3 . The star-shaped compounds are high-spin (HS) systems at room temperature. On cooling to 20 K some of the iron(III) centers perform some HS–HS transition.
