Abstract

Heptacoordinated metal complexes with a pentadentate ligand 2,6-diacetylpyridine-bis(thiosemicarbazone) (H₂daptsc) were used for the first time ever as building blocks to create polynuclear multifunctional molecular materials. Reactions of the paramagnetic [Mn(II)(H₂daptsc)(H₂O)₂](ClO₄)₂ and [Mn(II)(H₂daptsc)Cl₂] complexes with photochromic sodium nitroprusside Na₂[Fe(II)(CN)₅NO]^.2H₂O were studied. As a result, six polynuclear phases were obtained: {Mn(H₂daptsc)Fe(CN)₅NO}_n·0.5n(MeOH)·0.5n(H₂O) (1), {Mn(H₂daptsc)Fe(CN)₅NO}_3n·8n(MeOH) (2), {Mn(H₂daptsc)Fe(CN)₅NO}_2n·n(MeOH)·n(H₂O) (3), [Mn(H₂daptsc)Cl]₂[Fe(CN)₅NO] (4), {Mn(H₂daptsc)Fe(CN)₅NO}_n·2n(H₂O) (5) and {Mn(H₂daptsc)Fe(CN)₅NO}_n·n(EtOH) (6). The crystal structures of the phases as well as the magnetic and photochromic properties of 1 and 4 were studied.
