Abstract

Abstract : Metal complexes with H2 daptsc ligand were first used as building blocks to create polynuclear multifunctional materials. Abstract : Heptacoordinated metal complexes with a pentadentate ligand 2, 6-diacetylpyridine-bis(thiosemicarbazone) (H2 daptsc) were used for the first time ever as building blocks to create polynuclear multifunctional molecular materials. Reactions of the paramagnetic [Mn(ii )(H2 daptsc)(H2 O)2 ](ClO4 )2 and [Mn(ii )(H2 daptsc)Cl2 ] complexes with photochromic sodium nitroprusside Na2 [Fe(ii )(CN)5 NO] . 2H2 O were studied. As a result, six polynuclear phases were obtained: {Mn(H2 daptsc)Fe(CN)5 NO} n ·0.5 n (MeOH)·0.5 n (H2 O) (1 ), {Mn(H2 daptsc)Fe(CN)5 NO}3 n ·8 n (MeOH) (2 ), {Mn(H2 daptsc)Fe(CN)5 NO}2 n · n (MeOH)· n (H2 O) (3 ), [Mn(H2 daptsc)Cl]2 [Fe(CN)5 NO] (4 ), {Mn(H2 daptsc)Fe(CN)5 NO} n ·2 n (H2 O) (5 ) and {Mn(H2 daptsc)Fe(CN)5 NO} n · n (EtOH) (6 ). The crystal structures of the phases as well as the magnetic and photochromic properties of 1 and 4 were studied.
