| Abstract: | The first heterometallic chain cluster {[Mn4(hmp)6(NO3)2FeNO(CN)5·4CH3CN}n (1) based on the [Mn4(hmp)6] SMM has been synthesized. 1 has one-dimensional chain structure: the [Mn4(hmp)6] units are linked via CN-groups of nitroprusside anions. Its magnetic and relaxation properties and low temperature IR spectra under light irradiation have been investigated. The ferromagnetic exchange constants have been calculated. |
