Tetraaqua-1κ4O-bis(ɛ-caprolactam-1κO)-μ-cyano-1:2κ2N:C-pentacyano-2κ5C-iron(III)yttrium(III), a novel cyano-bridged dinuclear complex

Using caprolactam as a ligand, the novel title cyano‐bridged yttrium(III)–ferricyanide complex, [Y(caprolactam)2(H2O)4Fe(CN)6] or [FeY(CN)6(C6H11NO)2(H2O)4], has been synthesized and structurally characterized. The Y atom is seven‐coordinate and has approximately pentagonal–bipyramidal stereochemist...

description Using caprolactam as a ligand, the novel title cyano‐bridged yttrium(III)–ferricyanide complex, [Y(caprolactam)2(H2O)4Fe(CN)6] or [FeY(CN)6(C6H11NO)2(H2O)4], has been synthesized and structurally characterized. The Y atom is seven‐coordinate and has approximately pentagonal–bipyramidal stereochemistry, with water mol­ecules occupying apical positions. Of the five ligands in equatorial positions, one is the N‐bound bridging cyano group, and flanking this are two O‐­bound caprolactam moieties, which are markedly inclined towards the bridged ferricyanide moiety such that they partially envelop it. Water mol­ecules occupy the remaining two equatorial positions. The Y—N—C—Fe—C—N sequence of atoms lies on a crystallographic twofold axis and is therefore perfectly linear, which has not been observed previously in cyano‐bridged bimetallic complexes.
