Cyano-bridged polynuclear coordination compounds derived from paramagnetic [Mn(H 2 daptsc)] 2+ and photochromic [Fe(CN) 5 NO] 2− building blocks
Heptacoordinated metal complexes with a pentadentate ligand 2,6-diacetylpyridine-bis(thiosemicarbazone) (H 2 daptsc) were used for the first time ever as building blocks to create polynuclear multifunctional molecular materials. Reactions of the paramagnetic [Mn( ii )(H 2 daptsc)(H 2 O) 2 ](ClO 4 )...
